There are a lot of people around in Darrow who look like other people, and it'd be fucked up, but probably not impossible that someone with his sister's face would show up in his building. Though, she immediately recognizes him, and he's not sure whether he's pissed at her for showing up or pissed at her for taking so long to do it.

"New hardware?" he asks, because he doesn't know where the hell to even start answering her other questions. It's gonna sound fucking crazy no matter how he puts it. Plus, Fiona didn't have an ankle monitor when he left home, so he's got no idea what she remembers happening.
