Jack Howl,

After a study session with Jack that had been much too long, you wound up deciding to crash at his dorm for the night. Not to do anything weird, you just didn't feel like going all the way back to your dorm.

However, since you didn't want to share a bed with Jack, you just threw a blanket on the rug next to his bed and called it a mediocre, not-even-a-sleeping-bag.
You didn't even know how long you lay there staring at the ceiling, but it had been a while before Jack suddenly called out to you.

"You're still awake?"
You heard Jack ask in a hushed voice.
You grabbed your phone, opening it to check the time- one in the morning.
Okay, it's not that bad. At least it's not three in the morning...

You heard Jack let out a soft huff, and the shifting of blankets as he got out of his bed (from the other side to avoid stepping on you) and walked over.
"Look, the way you're sleeping is going to destroy your back. We can share my bed. It'll be fine."
