Remember, she studied his planning notebook, so they had everything scripted out. When Daniel Kaluuya showed back up...they weren't surprised, she knew from what happened at the bowling alley that his tendency was to follow behind folks. So they feigned being unprepared, and had a vehicle ready once he popped up to rob them. Same with Liam showing up. She knew it was coming, but the question was whether he would actually try and kill her...and she was prepped for that too.
