The Magnus and Kravitz friendship is something that is so important to me. Magnus took one look at Kravitz and said "This man needs a small, adorable, frisky, and yes, sometimes yippy and annoying dog" and packed one up to bring over.
Because they both know the dog isn't for Kravitz, it's for Taako, too. They both know how he's been a bit distant and weird lately. Talking about how he doesn't do magic anymore and all that nonsense. I think Kravitz is far more of an open book, and probably confided in Magnus how he's worried about Taako. His "we'll talk about this later."
It's just... *clenches fist* the care
Watch me reading too far into probably inconsequential details!!!!!
