Russell (Dermot Mulroney) who? Judging by the teaser images for New Girl's 23rd episode, "Backslide," Paul (guest star Justin Long) may be poised to reenter Jess's (Zooey Deschanel) love life.

Is the engagement bling in the below photo intended for Jess, or has Paul fallen for another quirky, feelings stick-wielding teacher at the school? (Doubtful — is there room in this world for more than one Jess?)

We'll have to wait until May 1 for some definitive answers. The anticipation may kill us. For reals.
