Luke had been in Alexandria hanging out at that temple he probably shouldn't be hanging out at when he got the message. Luckily his powers gave him the chance to get back to the dorms without a ton of walking, which meant he didn't give himself a lot of time to get broody over things.

Which was for the best 'cause really the last thing the world needed was a Anakin/Luke brood-off.

He knocked on the door to the office and tried to force himself to keep a calm, collected attitude about everything.
