Rachel wouldn't say she's been
babysitting for a number of different reasons. A few of them include Not Wanting to Get Punched, Not Finding Anything Funny About the Situation. First and foremost being that she doesn't consider what she's been doing babysitting in the first place.
She's hoping it could be considered 'helping,' but she's relying on Jo's responses to tell her if that's accurate or not.
And 'with Jo' is where she's been the last few days, wandering around Metropolis, dropping in on the woman's apartment - invited or otherwise - making passes over the city in eagle morph. Surveillance, of a sort. She won't look specifically for Dean or Jack because she refuses to go over Jo's head like that for information. But if she happens to see something while she's up there that explains what happened...
Well, that's not her fault.
Right now, she could be found in the sky. Or maybe it's late and she's heading back to that building she and Tobias have been staying in. Or maybe, just maybe, someone's going to catch her on her way to or from checking on Jo.
...not that she needs checking on. Of course.
