Her hotel room card.

Jason: Little difficult to get into your room without your keycard, yeah?
Jenna: Funny. Jill just let me in.

And then, 3 minutes later.

Jason: You ok?

Jenna:ur sweet. Im a big grl, I make my own decisions
Jason: I know you aren't free I just think ur awesome.
Jenna: thnx. g2g. Maybe i'll bump into you again before we leave.

The water shutting off snaps you back to reality. You quickly forward the rest of the conversation to your own phone, and then home Jenna's phone and throw it down. There was still no evidence that she did anything that you can't forgive. But...there were more texts between that last one and the one that came today. This story isn't done.
Jenna steps out of the bathroom. She's scrubbing her hair with a towel, but naked otherwise.
"Oh! Morning, baby."She saunters over to give you a peck on the cheek.
