That ended the battle scene, and we cut to the castle. With the reserve garrison and the returned troops there were 22 archers, 36 men-at-arms, 18 sergeants and 3 knights, plus Sir Andreas and his castellan Sir Satyrion, and the PCs and their 12 men-at-arms: a total of 96 defenders. The penalty for being outnumbers two-to-one is -2 dice; the penalty for assaulting the castle is -4 dice; and so the players were reasonably confident they could hold the castle against assault.
And so everyone dined.
The scenario I was drawing on here is in the Prince Valiant Episode Book - The Littlest Prince - but our framing was rather different, as the castle's army had returned rather than having been routed. So I asked Sir Morgath's player to roll his Fellowship + Presence (7D) against an obstacle of 3 (I think it was), and he succeeded. I told him that he noticed that Sir Satyrion seemed rather sour. Morgath first spoke to Sir Andreas, and (with successful Courtesie) confirmed his suspicion that it was Satyrion who had suggested that they sally forth. (The conjecture was the players, and it certainly fitted with the scenario backstory.)
He then consulted with the other PCs, and decided to speak to Sir Satyrion, to try and learn his motives (eg power-hunger; loyalty to the Arab rather than the Greek cause; etc). This was Glamourie, and the player was rolling 8 dice (Presence 4, Glamourie 2, +2D for greater fame and his prestigious accoutrements). So he was quite successful. First, he learned that Satyrion was jealous of Andreas, and mocked him. When I asked Morgath's player if he likewise mocked Justin and Gerren, he replied "Not Sir Gerren". I asked Sir Justin's player to make a Presence check to see if he overheard the mockery; he did. Justin's player had Justin declare that he was finished dining, with the intention that he would go to the infirmary and tend to the injured; I called for another Presence check to see if he could really hold his pride in check despite Sir Morgath's word. This succeeded too, and he then rolled very well on his healing, further cementing his order's reputation in Cyprus.
A second Glamourie check succeeded, and Satyrion asked Morgath whether he was married. Sir Morgath started to speak of his love for his wife Elizabeth of York - I asked for a Presence check to avoid also speaking of Lorette of Lothian, who he left in Toulouse but still longs for. The check succeeded, and so Lorette didn't come up. Satyrion explained that he wished to marry Flora, Andrea's teenage daughter; although this would not make him the heir, as there was also an infant son, Theo. Satyrion also asked Morgath if his ambitions lay in the East, but Morgath responded that he hoped the crusading urges of Justin and Gerren would soon be satisfied so that they could all return to the West, and Morgath could return to his duties in York. (Morgath's player explained that Morgath isn't really a liar, and that his Glamourie is mostly just for helping resist seduction.)
I explained that this seemed to quieten Satyrion, and asked whether Morgath wanted to pump him for any more information. A third successful Glamourie check was made, and Morgath suggested that he might be able to help Satyrion with his plans with Flora. Satyrion, his guard quite lowered, asked whether Morgath was intimating that he might help with a plot against Andreas and Theo; Morgath replied that he was just referring to wooing! And so Satyrion excused himself.
I asked Sir Gerren's player what Gerren was doing. The reply was, checking the castle's defences. I said that a roll of Battle + Presence (9 dice) could strengthen the defences on 5 or more successes (ie give another die penalty to attacking forces), while two or fewer successes would mean something had gone wrong. Naturally the roll was two successes! As Sir Gerren was at a tower battlement, backlit by torches, an arrow struck him for 1 point of Brawn lost. I then said that he could see someone - a spy - who had infiltrated via the postern and was trying to open the main gate. I asked Gerren's player whether he was prepared to leap from the tower to stop the spy, as Tintin would. He was. I can't recall the difficulty I set - 4 or 5, I think - with every success short of that on Brawn + Agility being a point of Brawn lost in the landing. With Brawn 4 and no Agility skill, 2 points were lost, leaving Sir Gerren with only 1 Brawn to brawl with the spy. Their first round of brawling did not let the spy get to the gate, but nor did Sir Gerren disable him. Sir Gerren called for help, and with a success on his Presence + Oratory check guards came running and the gate remained closed. But about this same time, Flora announced in distress that Theo was missing from the nursery! Sir Morgath spoke to the servants in the castle, including the basement (Fellowship + Presence, with good successes) and they had seen nothing; Sir Gerren looked out from the battlement, and might have seen the riders leaving where Satyrion had spirited Theo out the postern, but failed his Presence check.
Down in the courtyard, Sir Gerren could see that Sir Andreas was getting ready to ride forth searching for his son. He tried to persuade him to hold off, that this was too big a risk to the defence of the castle; but failed: Sir Andreas reminded him that when his son (Sir Justin) had been in trouble, he had risked everything to rescue him (ie in the battle earlier that day). But Sir Andreas agreed that Sir Gerren, Sir Justin and their troops could ride with him. An oratory check mustered the men, although it was one success short of the difficulty I'd set and so they were at -1 for fighting due to the rapidity of the mustering (loose saddles, poorly donned armour, etc). And so Andreas rode out with 2 of his house-knights, 3 sergeants and 6 men-at-arms, as well as Sir Justin, Sir Gerren, their scout Rhan, and their 12 men-at-arms. Sir Morgath's player insisted quite forcefully that his scout retain, Algol the Bloodthirsty, was remaining with him in the castle. It was only once the posse had ridden out, to the echoes of me the GM saying "no backsies!", that the players fully computed that their two commanders with Battle 6 each had left the castle under the command of the teenager Flora and Sir Morgath with his Battle 1.
