How she can sleep in this noisy place is beyond him.
Ah, but she is the powerful Light Side user now. This probably sounds like a lullaby to her, and it's like an amphitheater full of scolding voices to him. Not threatening, only – forewarning, inquisitive, and even slightly ironic.
At first, he cannot sleep and doesn't expect himself to. The forest is full of nocturnal murmurs and he very well knows not all of them belong to welcoming life-forms. There is something in front of that door that sniffs the air and doesn't appreciate the intruders inside. But something else – something even more predatorial in nature – scares it off.
He has his remaining weapons with him. His saber, his blaster gun – foolish girl, for not disarming him as they landed. Foolish girl, for saving him in the first place. He couldn't believe his eyes when she came with the silencer, roaring engines, utter boldness and that fire of hope that can't be extinguished. He knew in an instant the First Order was doomed, the minute she appeared on the Imperial Palace.
Foolish girl and a true Jedi.
Snoke was right.
His eyes wander. She is cramped on that bed in fetal position, back turned to him. She kicked off her boots and he sees holes at the soles of her socks. Her tan pants are stained with mud, and they both smell of… Dagobah, actually. It's almost comical. She breathes in and out peacefully in her sleep. Clean conscience – that's what it feels like. He didn't have that in years, in a whole lifetime.
Her cape has that faint scent of her, more an energy than anything else. The whole previous day comes back to him, but from her perspective. The denial, the doubt, the conflict, the "Falcon", the pilot, wookie – her admiration for Coruscant (yes, it is exactly as she sees it, the mystical place of decaying beauty and yes, if there was something remotely resembling home after he deflected from the Jedi, it's that planet) and the blink-of-an-eye decision to come to his aid.
He dozes off eventually with those memories stuck in his mind and with her scent in his nostrils and those are 2 hours of the most uninterrupted sleep he has had in years.
