This girl has baggage. She was upfront to him about it. She couldn't afford not to be - not after everything else that's happened and all the other groups of people she's (literally) gone through in the recent past. Keeping secrets always came back to bite her in the ass. Whether or not he chose to believe her was up to him and him only. He signed up for this when he decided to let her tag along. At least - that's how she attempts to justify things to herself.

She's kept a low profile while waiting for him, crouched and quiet in her hiding spot. They're not stupid. There's a huge chance they already know she's on their tail. But at least she's trying to remain under the radar for the meanwhile.

When she hears the familiar whistle she perks up, then takes a look around to scope out exactly where it's coming from. Once he's in her sight she smiles and gives a little wave, then gestures for him to come meet her.
