6 Gavin Mitchell
Dated: Rachel
Pros: Though kind of a dick at first, Gavin turns out to be really charming and a great match for Rachel. Plus, they have so much to talk about, given that they worked the exact same job. (Awkward.)
Cons: There’s a bit of a rivalry there that makes for sparks but also puts them both in an awkward position. Inevitably, Rachel’s just not that into him — or rather, she’s too confused about Ross to pursue anything.
