I've had this in the back of my head but didn't want to say it - going to put it out there in case anyone else is thinking the same.
Was it not initially stated "BT will be found wearing X"? (since the specific clothing titles are up in the air)
If so, that seemingly could infer that it's known that she will be (or should have been) found wearing X.
Wandered down that thought train during some of the underwear discussion. I'm sure I'm walking a fine line on the rules with this post, feel free to nuke it if needed.
Edit for clarification: The statement seems to be made in a definitive tone, when it should have been made in a presumptive tone. You don't know what she will be found in as she has yet to be found. Maybe I'm thinking too far.
I think it's a reasonable thing to wonder about, but would want to double-check whether he actually said those words. I don't remember it, but that doesn't mean it didn't happen.
