Normally I would call the whole "She's not actually dead" thing a cheap trick, but on the other hand she is a spider and that is a thing they do, so it doesn't seem unreasonable she'd have that power.
@damakuno Yeah, one the one hand she's cute and it's good she's turned over a new leaf.
But on the other hand she's killed and eaten humans in the not too distance past...
Like, if she were hundreds of years old and hadn't done it in over 100 or something
than maybe I'd be able to be less concerned, but that ain't the case here...
