Luna nods and offers her own hand for the shake. "It's been good to meet you, Karkat. Thank you for all your help." She has a lot to think about now, thanks to him. Expectations, preparations, next steps--she'd written off the training in the gym earlier, thinking that they wouldn't be of use to her, but maybe not. She could take advantage of a few things, at least, to help out in the Arena. It's a good feeling, and it shows in how her mood's brightened. "And yes, I'll see you later. I think I'll go downstairs to see those training stations. In the meantime, good luck with your writing!"
