Rey likes to think that Han would appreciate her taking such good care of the two most important women in his life.
Hadn't he offered her a job on the Millennium Falcon after seeing how well she'd handled her, what an immediate instinct she had for it?
It makes her feel less guilty about what she's doing and to whom.
The Falcon rattles less now, takes off a little more smoothly.
Leia works less, sleeps a little more soundly.
She can understand why it was hard to give up a life at light speed.
She can't understand how he could have given up Leia though. She didn't buy that it was for Leia's own good, so she'd hurt a little less if she didn't see their son in the lines of his jaw every day.
Maybe she'll make the Kessel run in twelve parsecs one day herself, but right now she'd rather be the one who made Leia happy again.
