Well here are two bits of information that probably deserve a minute of consideration before a response is given. For one thing no one's told Wyoming that death isn't permanent around here yet. considering all the things he's seen so far, it doesn't seem outside the realm of possibility, though and Wyoming is trying to not show off what he does and doesn't know so he's not even going to question that right now. He can ask people who don't know his reputation so well.

Which leaves the actual offer itself to think about.
"How do we know you won't keep or, for that matter, delete him during my absence? I'm afraid it could be a bit hard to check up on you two should such circumstances arise."
