Where is Trelawny.

I'm in chapter 6, the only mission I have currently is Icarus and Friends, Trelawny and his horse have both been gone from camp since Angelo Bronte, A man of honor but he was there for the mission A Fine Night of Debauchery and I haven't seen him since then. Is my game glitched or what?? I've been looking for him for like 2 days now.
