Danny definitely has that side to him too, but he's overcome most of it by now. Still doesn't trust groups of humans to do what's right but other than that... I think they will balance each other out.
Oh they're going to get on like a house on fire. Danny hates cooking. He's more likely to take bear shape and eat things raw than mess around with a fire. And he is exceptionally fond of alcohol in all its forms.
I can just picture Danny reeling in a fish and then calling out, "Witch, come get a fire going! And pour us a drink!" as Varu is on a nature walk.
