We missed Caleb (Tyler Blackburn) this week, but fortunately he's back on Pretty Little Liars Season 3, Episode 16: "Misery Loves Company."

In this sneak peek of the episode, he tells Hanna (Ashley Benson) he's worried about Mona (Janel Parrish) being back — so worried, he's even sharing his concerns with his mom. You know, the one "A" almost ran off the road? Yeah.

Caleb's worried about Hanna, Hanna's worried about Caleb, and we're worried that they seem so happy together. The writers love to screw with PLL ships just when they seem to be at their strongest...
