Concept: Keith during his first night with the Marmora after saying goodbye to the team, staring up at the ceiling and just. feeling lonely. He doesn’t really get why– he’s been alone for years, he should be used to this by now. And he’s laying there trying to convince himself of that when suddenly the room lights up and he glances over to find his communicator (”space cellphone,” Lance had said helpfully behind Coran’s back) blinking with incoming messages. "I’m proud of you,” says Shiro. "Be safe,” says Allura. "Good luck,” says Pidge. "I miss you!!” says Hunk. "Come back soon,” says Lance. And it just really hits Keith that. Wow. For the first time in a long time, he has a home to go back to and people who miss having him there.
