You could time-jump to morning and have him wake up (at which point Jack'd describe what transpired in the tavern meanwhile)? How would Kaedan react to the barkeep's offers; simply take the first one and not discuss further? 
((Ehh... If he is as tired as you make him seem, I'd understand if he didn't wish to discuss things further at the time being, or even think over them too much.))

 - I believe there is very little chance Kaedan would be meeting another played character before a bit later in the next day; almost definitely not in this inn.

(Just throwing out suggestions here.)
