Sarah is anxious. One: because she's already done this already, and two: because the last time she did it, the circumstances were hugely different. This time she's dragging a Helena who's still uncertain how she feels about other clones to meet a Cosima who barely likes Sarah at this point, much less Sarah's troubled twin. She gives a withering glance to Helena and her pointy metal, thinks about confiscating it, then decides that might make everything worse.

Okay. New plan. She stands from her seat at the table and places a hand on Helena's shoulder.

"Stay right here. Don't cause any trouble. I'm going out front to meet Cosima." She gives Helena a pointed look before heading for the door. "I mean it, Helena. I'll be right back."

Once she's outside, she runs a hand through her hair and then sticks both hands in the pockets of her jacket, slouching against the tavern wall and keeping an eye out for Cosima.
