Fiona’s love life on Shameless is about to get even more complicated.

After her ex-boyfriend, played by Justin Chatwin, returned at the end of Season 4, it appears Fiona (played by Emmy Rossum) will be getting a new love interest in Season 5: her boss, played by Dermot Mulroney.

According to THR, Mulroney has signed on for the season to play Fiona’s manager at Patsy Pies, and the two will enjoy a rather flirtatious relationship. Given that this is Shameless we’re talking about, we don’t really expect things to remain platonic.

The show won’t return until sometime in 2015, but we’ll be hearing lots more about it before then. That’s because Shameless picked up three Emmy nominations this year, for performances by William H. Macy and Joan Cusack, as well as the show's surprisingly good stunt work.
