We thought the physicality of this character would be mirrored by Liliths interpretation of who Jonathan is.

Is the Owl face all CGI?Its not CGI at all.

That was an exploration.

Its a pretty rough day.

Theyre also tinted, and it was night so everything was really dark.

Then what we found out is that the masks leaked and the lenses started to fill up with water.

Because every time this creature possesses someone, he kneels over them and holds their face.

And sure enough, I kneeled down and [my pants] ripped all the way through.

He still has no idea whats going on.

Hes the last person to find out, and as far as his reaction, its not good.

We also havent seen the worst of the Owl yet.

It gets much, much worse.

This is about revenge for Lilith more than anything.

Shes going to take a mean swing at it, trust me.

How does being the Owl affect his relationships?The relationships are tricky.

Its difficult, like when Alec approached him about losing his mind, he snapped at Alec.

Its this creature trying to destroy Jace through his friends.

Its really quite awful.
