Different windows are open at different times of day. It's usually the attic, but right now, in the dark, it's the girls' bedroom. Andi is in it.
And then he is too far gone in his demorph to continue speaking, and he finishes up and heads downstairs with a wave.
And there is Bella, in the kitchen with Renée. Bella is writing (as always) and Renée is mincing an onion, presumably to add to the crockpot.
"Okay. Basement's empty, Charlie's doing a stakeout kind of thing." She motions Trouble to follow and heads downstairs.
"So I met this girl," he starts, "she feeds pigeons in a park across town, and she talks to them, and she's really cute, so I followed her for three days to make sure she's not a Controller and then said hi. As a pigeon."
"She's really cute," he reiterates. "We talked for a while and I didn't bring up aliens or use any sensitive vocabulary but I told her not to go near the Sharing and that I'm a shapeshifter, and she took me home and recognized me from a newspaper ad but she's not gonna turn me in 'cause I told her I ran away for reasons, and then we made out for like three hours, and can I make her an Animorph? Maybe?"
"There was enough advance planning involved for you to follow her for three days but you wait until now to tip me off?"
"Yeah," he says, "it's not like I planned in advance to follow her for three days, I just kinda started, and time spent figuring out how to tell you what I wanted to do and then telling you would've been time spent not doing it."
"And they didn't say 'stalking cute girl to see if she's a Controller', let alone 'planning to thoughtspeak to cute girl', and now if you've made a mistake she knows you're a human and has personally identified you, and if she's a blabbermouth..."
Bella drops her head into her hands. "Do you know if her parents or siblings or friends are in the Sharing? Do you know if her teachers or neighbors or clergyperson are Yeerks?"
