I expect there will be silver in the lab, I'd be amazed if there wasn't. The notebook has the thing's dimensions, I'd consider constructing a containment case for it through some means.

[No, Alucard, there's no silversmithy here. But there's Sypha and her fire, and that's even better.

And it's...easier to let Trevor take the lead on this. Fewer messy emotions that are placed squarely on Alucard's shoulders. (That's unfair though, isn't it? Even if this counts as squarely Belmont Things. One family cleaning up the mess of another.)]

And there can be additional warding spells and the like put in the case once it's constructed.
