It is an idea that Damon is going to go through with.

He weighs how long it would take Stefan and Elena to discuss this versus how long it would take him to take matters into his own hands. Damon has already started looking into it, knowing Elena was going to do so. Maybe he can beat them both to the punch and take on whatever consequences this ship wants to hand out.

"To sum up, the world that I ended up in is... terrible, and I've been there a very long time." Damon swallows thickly as he folds his arms across his chest, shutting out a lot of things that threaten to-- "And I don't want to go back."

He would give anything to not have to go back so getting thrown off a magic ship? Doesn't seem that terrible. Seems preferable.
