It may not be as dramatic as their last tussle, but there is some serious tension between Spencer (Troian Bellisario) and Mona (Janel Parrish) in this sneak peek for next week’s Pretty Little Liars episode (Season 3, Episode 21: “Out of Sight, Out of Mind”).
 
In the clip, the Liars are hanging at Emily’s (Shay Mitchell) coffee shop when Mona walks in. Spencer confronts her about the flowers they received. We are guessing she is referring to the “deepest sympathies” arrangement one of the “A” Teamers was putting together in the epilogue to last week’s episode (Season 3, Episode 20: “Hot Water).

“You so much as touch one hair on their heads, I will make you very sorry,” Spencer tells Mona, Hanna (Ashley Benson)in tow.

Spence’s threat doesn’t phase Mona. Though she denies sending the flowers, she can’t resist giving Spence the following advice: “Be sure not to leave them in direct sunlight. I did once. They didn’t make it through the night.”

As evil as Mona can be, we can’t help but love her passive aggressive tips, especially when she suggests to Spencer in this scene that it “might be time to visit your doctor friend again.” We can’t help but agree with evil Mona. Dr. Wren is adorable!

Looks like Spencer is back in fighting mode. As much as we enjoyed Troian’s performance as Spencer hit rock bottom, we did miss this side of her. Her one-liners just aren’t the same when she was feeling sorry her herself.

Are you glad to see Spencer back on the offensive? Do you think it was a mistake to threaten Mona? Let us know in the comments below!
