Even when he's not at Hermione's side trying to learn, Danny doesn't slink too far away. He has a couple people around he knows are magical, and he's got his eyes on them all, but she's the one who's been most actively welcoming and accepting. He's going to follow her lead.

His inclination when he hears the building collapse is, frankly, to hide. He's not really hero material. But while he freezes to the spot for a long moment, once shes headed outside, he follows, and--

He knows that man. The one standing there pouring out magic to lift the fallen material of the building. That's Maxim Horvath and the sight of him is enough to make Danny want to pivot and run for the goddamn hills. How has the Eldest Morganian been in the Nexus all this time and no one's even noticed?!

He'd probably either stand rooted where he is, or turn tail, except Hermione calls for help. He looks at her for a moment, gaping, then at Horvath, and then--well, shit. Okay, this is what they're doing today, clearly.

He casts a bright little magelight in the palm of his hand and races toward the building. "MARCO!?"

There's a pause before a panicked, crackling voice yells back, "POLO!"
