When Wu asked what Monroe was doing there, I thought, "Well, you know he's a friend, and Nick's using his personal car, not his police cruiser; is it too much to think that they were doing something together when the call came?"
As for what Trubel will do, I agree she can't live with Nick and Juliette, but now that Rosalee has moved in with Monroe, the apartment over the shop is vacant. Perhaps she can trade a few hours/week work in the shop for living space. Nick has made enough connections with people that he should be able to find her a job and get her enrolled in community college.
I think also as well as introducing her to Monroe and Rosalee, he should also get her together with some of the 'nice' teenage Wesen. Like the Coyotl girl, or the Reinegen boy, or the Blutbad girl who lived in the forest (that last especially, as her experience parallels Trubel's a bit.) (Does Bud have any nieces or nephews her age? Who can be scared of Eisbiebern?)
