I'm not objecting to taking her and she is probably twenty times smarter than I am about all of this. But she can use her mind in a safer location than right on the doorstep. That's all I'm saying. She can direct us from a couple of floors away in the casino just as easily as she can in our back pockets.
And I get that she's immortal. I still can't fight the really, really adamant urge here, unfortunately. Sorry.
