[Hiccup has always been too nice for his own good, Jack knows that, always have. He actually likes that about his husband, it makes him believe in a better world after a not so happy childhood... now though. He's fucking pissed, and he has no patience to even consider keep anything that comes from Pitch, specially something that can eat them while they sleep.

Seeing as he can't keep Hiccup away from the panther, Jack lets go of him and throws his arms in the air in frustration.]

Who said anything about destroying it? They can take it to a zoo or back to the jungle or whatever! [He looks at Hiccup clearly not believing what's going on.] Come on, Hiccup, it's our honeymoon! We can't spend it taking care of a fucking panther!

[Later he will hate himself for reacting like this - the animal hasn't done anything and it's still ruining their special time together. It's gonna be really hard to stop Jack from punching that asshole next time he sses it. Because dammit.]
