After the war, Seamus and Dean manage to get their shit together and finally begin dating. (Their friends breathe a collective sigh of relief–including Hermione, who Seamus tells to piss off; it took her just as long to get together with Ron, for gods sake.) They settle down in London (Seamus isn’t happy about it, but he’ll go with what he gets), in a pretty house near the forests. Dean paints, Seamus writes, and, for two guys with abandonment issues and dripping sarcasm, live as happily ever after as possible.
one of the things i find really interesting about the snape/lily/james triangle (that it seems like a lot of people miss because idk some people have seriously messed-up ideas of relationships) is that it very, very clearly shows, at every point, the difference between love and obsession.
