There are a lot of good choices in here. but i went with trelawny. for one he is not used much in the main story. and for two i don't even know if i saw him and john interact. i don't think they are in any missions together. so it would be cool to see them meet and talk.

We know that Trelawny probably went back to his family in Saint Denis following his departure from camp, so I think it would’ve been cool if you saw him walking or riding with his sons there in the epilogue.

Of course Mr. Trelawny! He is my ravorite character

None of these, perhaps rather o' Strauss, see how's he hangin' about, hehehehe.

Mary Linton n Trelawny

You can encounter Trelawny in Saint Denis during the epilogue. I did after doing a Charles Chateney mission.
