She hadn't been debriefed yet. Hell technically she wasn't even supposed to be here. She'd been told to stay home until things had calmed down and they had the chance to talk to her. But upon hearing that Zinda had been locked up, Jemma figured that a friendly face couldn't hurt.
SHIELD hadn't even let her come inside for very long, so she was waiting outside the building when Zinda walked out. Jemma walked over to her and held out a hotcup for her to take. "I heard you were here... thought it might be nice to not go home on your own. Oh," she looked at the cup. "It's coffee. With something stronger in it. I thought you'd appreciate it after all this." She was smiling but it wasn't reaching her eyes. And after their ordeals, who could blame her?
