Sam can tell her mind has been made up about this. At least he's got her to agree to sleep in his bed and if it's at the price of him joining her then so be it. It's just that the last time they were in his bed together, they were naked. And Sam's afraid he's going to end up cuddling her in his sleep, something she might not want.

"Are you sure it's such a good idea?" Sure, they're friends. Friends can sleep in the same bed together. But they'd crossed the line of friendship the other day and they can never go back.
