Dude, please! Jesse is so not with Tara!! If you block out their smiles then you can see in Tara's (intoxicated) eyes there is sheer desperation and in Jesse's eyes fear. Tara is obviously trying to get with him and he so obviously doesn't wanna be near her. Duh! Just look at her eyes and desperate grip on his shirt!
Dude, she was probably so drunk that she thought he was a beer and was hanging on for dear life cuz, oh God forbid, Tara does NOT let her beer out of site!

Peace and God bless
