I see how you got there... but I can also see them coming through a rough patch and arriving at a happy (enough) ending, because sometimes what's attractive is someone's otherness. El and Neal have a lot in common, but maybe one of the things they have in common is wanting and loving Peter because he is different.

Dunno, just thinking about my own relationships, and the difference between the people I share interests with and do things with in comparison with the people I fall in love with and/or want to have sex with.
