He's been busy. With Rose being a baby and needing attention, Mia acting strange and snappy, and the BSAA constantly on their back, Ethan's been left little time to devote to his other kid, and it's made him feel a bit guilty.
After hours of Rose fussing—and in turn, ignoring his eldest—she eventually settles down, is put down for a nap, and Ethan can finally find the time to spend with the other.
Ethan quickly made his way up to the kid's room, knocking before he peeked his head in. “Hey, sweetheart! Was wondering if maybe you'd like to go on a walk? Just you and me? It's snowy out, so you'll have to bundle up,” He asked with a bright smile.
He's been looking for a chance to focus on you, and hopes this will suffice for quality time. He just wants you to be happy.
