This Week’s Exclusive Secrets from Set: Finding out the Jace is, in fact, the Owl is a pretty big trip. What’s even trippier is that Dominic Sherwood has actually been under the mask this whole time instead of leaving it up to a stunt guy. Talk about going the extra mile!

“That costume is not an easy thing to fight in,” Sherwood reveals. “The mask is quite heavy. There are solid black lenses that are out of focus, so I can’t really see 100 percent, but at the end of the day it looks sweet, so it doesn’t really matter that much.”

At least Clace fans can be kind of happy to know that McNamara confirms the big choking scene is all for show and Sherwood’s hand was “barely” on her throat.

Shadowhunters airs Tuesdays at 8/7c on Freeform.
