Wrong again, if you fail once your passive perception, the creature is hidden for you.I understand the rules here better than you seem to.
The Pass Without Trace spell went away, and without that bonus to your Stealth check, the Rog/Rgr was able to see you with his Passive Perception (which is like 30, and since you chose not to roll again, I went with something like the average, as opposed to something near the max).
The rest of the combat proceeded as it likely would, with those PCs.
That was seriously nothing they haven't done. The only one I can't really predict his actions is the bard, who's just a bit of a chaos vector (but effective and a bunch of fun to have in the party).
Once.
You can't roll again.
