Adelaide nods over Isaac's promises about Rob, knowing it's all she can really expect - and honestly, she wants Rob found, but it would likely be vastly preferable if it isn't the Capitol who finds him. Rodeo finding him would be just as bad - as much as they cooperated for Adelaide's trip to the Dog Park, she is well aware that Rodeo has no love lost for her husband. Rob's only real chance is self-sufficiency, or if Archer himself were to find him first. It makes Adelaide frown, but there are more pressing things right now.
The phone is something she's been thinking over in her cell since she was brought in, trying to decide what the best explanation would be. She's decided on a healthy mix of unpleasant truth and white lies, and she doesn't have any guilt about delivering them. She is hard wired for survival. She presses her lips, lifts her free hand.
"My husband... is a very meticulous man," she finally says. "I've known that he keeps a damn close eye on the things that I do for a long time - long before I found my brother or had anything to hide. My brother was infamous, wanted, and I didn't know how Rob would react to having the Austin Cop Killer as a brother-in-law, so I didn't tell him. Jims gave me that phone, so that we could talk without Rob knowing." Her eyes are steady, just the very slightest bit imploring now. "When I realized what your goon was at my place for, the connection that'd been made, I panicked and chucked the phone. I thought... I won't lie. I thought just speaking to him, eventually knowing who he was, even though I never helped him, would be enough for Olinger to throw away the key." She presses her lips again, looks genuinely annoyed. "I failed to realize - at midnight in my bathrobe with a Terminator at the door and my husband missing - that if he didn't string me up immediately, the phone would have served as perfect evidence that I didn't help him or collude with him."
