Anybody knows why Daddy is so mad? I don't think it's just because of work.

A few options come to mind:

-He's been editing the Edd x Lancer shots and is jealous/mad/frustrated with that and or can't even edit a satisfying movie from it.
-He's pissed whoever he's waiting for isn't showing (maybe someone related to the actual proper movie script he's making)
-He's annoyed that Edd's there, not with him, but instead with what he sees as homophobic douchebags.

I like the first one. I'd go for that. (๑•ㅂ•)و✧

I guess it's a combination of all three?

I guess a mix of all of that...
