For Tuck's allocated XP for the candle shop battle, I might give his full amount to Custodio and the Sobla will get Custodio's amount. I haven't decided yet.
EDIT: I forgot that Custodio already got a full allotment of XP. Hmm, I might just divide Tuck's XP between the other PCs (and Custodio).
That would be 1,042 more XP for each character.
