Move over, Wren — there’s a new brown-eyed doctor in town. According to Spoiler TV, Joe Zinsman will play the role of Dr. Vargas in two episode of Pretty Little Liars Season 4. What will this mysterious doctor be up to? We speculate below.

We already have Dr. Wren (Julian Morris) and Dr. Sullivan (Annabeth Gish) in Rosewood, so what could the show need with another doctor? Well, there is a high incidence of accidents and people driven mentally ill by “A”’s machinations, so we suppose Rosewood Hospital and Radley must be constantly trying to fill positions. Perhaps Spencer’s parents thought she might need someone to talk to who wasn’t her sister’s ex-fiancé?

The good doctor could also be appearing in flashback form. We learned from Eddie Lamb that Toby’s late mother used to be a patient at Radley, and we know from Marlene King that Toby’s mother will be appearing in the first episode of the season (most likely in flashback). Could Dr. Vargas have been her doctor? If so, could he be related to the information that “A” will be holding over Toby in Season 4?

What do you think Dr. Vargas will be up to? Let us know your theories in the comments below!

Pretty Little Liars Season 4 premieres on Tuesday, June 11, 2013 at 8 p.m. ET/PT on ABC Family.
