Wouldn't it be wierd if overall, Justin wound up becoming friendlier (than at present) to Sarah than to Elliot (at present) after tonight?!
edit: I don't mean what if he winds up closer to Sarah than to Elliot. I mean what if the "growth rate" tonight of his friendship to Sarah is far greater than the "growth rate" tonight of any increase in his already friendship with Elliot.
I think Justin is very uncomfortable being a girl, and his only real motive was to be beside a male Elliot for a good long while, to judge his reaction. So already things are not going as he had anticipated.
Love the way Grace's antennae are playing with Justin's hair!
