"Jace." Izzy says, looking up at him. "Will you please sit down?"
"I can't." He says, running his fingers through his hair as he continues to pace the room.
"Why not?"
"I keep feeling all this nervous energy through my parabatai rune."
"Why?"
"I have no idea. Alec is never like this."
Jace sits down but gets up almost immediately and starts to pace again. He repeats this pattern for what Izzy thinks is hours until he finally collapses on the couch looking exhausted.
"Are you ok?" Izzy asks.
"I don't know. Now I feel like all I want to do is sleep." He says, laying his head on the back of the couch.

"What was going on with you last night?" Jace asks alec the next morning while him and alec are training.
"What are you talking about?"
"To begin with there was all kinds of nervous energy through our parabatai rune then all of a sudden the only thing I wanted to do was sleep."
Alec blushes but looks jace in the eye and says, "What did you expect, Magnus outlasted my stamina rune." Alec says, turning around, leaving jace standing in the middle of the room, stunned.
