Winn is on the cusp of confessing his feelings for his BFF, but it remains to be seen if he will ever get the chance. Episode 10 will bring Winn's (Jeremy Jordan) father into the storyline, and as you already know, his father isn't exactly Mr. Nice.

"Winn's dad is a supervillain," executive producer Andrew Kreisberg told Entertainment Weekly. "Somebody who is dealing with that shame, humiliation, regret, and emotion--Winn's been presented as a pretty happy-go-lucky, nice and sweet guy, but he came from a very dark place."

"You're going to get more of Winn and Kara in episode 10, which features the Toyman," Kreisberg teased. "There's some stuff that comes up in that episode that's going to change their dynamic forever."

Will this change be for better or worse? Viewers will have to tune in to find out. Catch the midseason premiere of Supergirl on CBS at 8 p.m. ET on Jan. 4
