No he doesn't leave for good, i think i read that he was on break.
Anyway they made him cheat, drunjen again with a woman in England, he confessed to Olli, Olli screamed a bit and talk a walk, he thinks a lot and come back with a deal, they open their marriage, if Christian has the right to screw up Olli will fuck around too, the face of Christian, this was priceless, asshole didn't that coming.
Don't think that Olli will do that, he's not the kind of guy.

But god, how Joe was beautiful, he aged beautifully.
