"It is, that's why it's called a backup plan." That had seemed obvious to her. Backup plan was meant for when everything else had failed, when there was nothing left to try. It wasn't a death wish, it was just realistic. "If I can't get away, I won't stay trapped." Simple school of thought there, which she paired with a shrug. It wasn't how she wanted things to go, but a person had to know what they were willing to do. "I'm still working on the entire plan," she conceded after a pause, "Or I would've made my move."
More threats was almost met with an eye roll. "Put your teeth away, I'm not involving either of them." Dragging either of them along was more dangerous than it would be helpful. Either because they wouldn't stick perfectly to her plan, or because they were her friends and that would likely result in her doing something stupid to help one of them. No, better they stay out of it.
Definitely approaching the shop with caution, but that would have been true even without his little song and dance.
"You can't stop me from calling you nice. And I think she would, Renata knows I wouldn't lie about something so trivial." Would it be as easy to bend her way out the window as it had in? Actually, she knew how to do it now so it seemed likely it would. Though she was halfway up the stairs now, Indy still hadn't turned around. She might be ready to call him nice but that didn't mean she trusted him not to decide to shoot her if she gave him her back, he was unpredictable that way.
At the top of the stairs she leaned forward slightly, so she could get one final look at him. "See you around." Maybe visiting Ren, maybe for other reasons - let him wonder if she'd attempt a second break in or not. And then she went for the window before he decided to follow her up.
