Additional BTS Photo for 3x13: Calezra On Set?

Here's an additional BTS photo from shooting 3x13, of two fan favourite actors of the PLL cast from TV Guide's Damian Holbrook:

"Calezra? Ezreb? Is this #PLL's new 'shipper sensation? @IANMHARDING @tylerjblackburn" (from Day 6 of shooting 3x13, see post here), with Damian confirming the photo was from "last night on set" - looks like both Caleb and Ezra will be at the Halloween festivities on the train in 3x13!

This is our first photo of our PLL cast in costume for Halloween 2.0 - we must say Ezra and Caleb are looking very smart! Ian doesn't seem to be dressed in anything, we must admit, too radical (slightly disappointing, but he still looks charming as always), but Tyler seems to have a costume of some sort, but it's hard to tell from photo!

With regards to the shipper name, we think we'd have to say Calezra, considering Ezreb sounds a tad weird, and Calezra sticks a bit more, although we think Hanna and Aria would have words to say about this ship!

What do you think is ahead for Caleb and Ezra in the Halloween episode, and their respective ships?
