Hmm... that's not the final scene of him I saw. I saw him sitting on the couch with his wife sleeping and his arm around her while he is watching a home video of them with their son, and the daughter comes in. This was after he had healed in the hospital after trying to commit suicide.

After the arrests there is a shot of Beth, the kids, and Det. Miller and her child all sitting down for an outdoor meal. Mark is not there and a cut away shows him driving off in his blue truck to points unknown.

In an earlier scene Beth tells him they can never go back to where they were in the beginning and that even before Danny's death their relationship was in trouble.

It would therefore seem that they are done.

he leaves in his van to try and find some peace of mind. he watched the home video after his suicide attempt.

I know he watched that after his suicide attempt. What I'm saying is, that's the last scene of him and the family I saw. So obviously I missed something that happened later. Weird, because I thought I'd watched the episode to the end. Oh well. Sad if that's what he ended up doing. I like the last scene I saw better, so I'm just going to believe for myself that he's still with them and things are OK now, lol. It's going to be my ending to myself for the show, lol. And no that doesn't mean I am not believing what you all are saying about him winding up leaving in the end, I just like the idea of him coming to terms with things and being OK finally, so since that's the last scene of him I saw, I'm sticking with that, lol.
