Would Kat and Patrick have stayed together?
On the one hand, Patrick is pretty much the only guy (apart from Joey Donner years ago) that Kat was ever interested in. And vice versa. So they had that going for them.
On the other hand, Kat is going across the country to Sarah Lawrence. We don't know what, if anything, Patrick plans to do after graduation. Does it seem likely he would follow Kat to New York?
