"...thank you." She sounds surprised, more than offended - it's hard to be offended by that kind of gesture when it comes from Steve, and she's still smiling as she slides into the cab.

She gives the driver her address and settles back, pointedly ignoring the odd looks the man keeps casting Steve in the rearview mirror. If she pretends there's nothing strange about two people catching a cab from a lab in Harvard in the middle of the night, one in a shirt that doesn't fit him at all... maybe the driver just won't ask. She can hope, anyway.

It's a short drive from Harvard to her house - fifteen minutes on a normal day, less at this time of night with next to no traffic - but Olivia all but vibrates with tension the whole way, drumming her fingers unconsciously against her thigh as she stares out the window. The last time she saw Rachel and Ella, she wasn't sure she would see them again, and now even a fifteen minute wait seems like an eternity.
