Fans of Hanna (Ashley Benson) and Caleb's (Tyler Blackburn) relationship have been on pins and needles for all of Pretty Little Liars Season 4. We know that Caleb is headed to Ravenswood so that Tyler Blackburn can star in the PLL spin-off, and many fans are worried that means Haleb will be over — and at the very least, we know that we'll be seeing a lot less of the pretty little couple on-screen together.

When will they say their goodbyes? We originally thought it was going to happen during the Season 4 Halloween episode, but it turns out Caleb is in the Season 4 winter premiere. Does he only show up to say sayonara? New tweets about the episode give us some clues.

Marlene thanked both young actors for their work:

Tyler said "it's been a dream":

And Chad Lowe (who's directing the episode) talked about being very moved by Ashley and Tyler's performances:
