Am i the only one thinking Robin is a two-faced?

I think Robin easily becomes dominated by those around her. THe expression on her face when Zara and Nadia teased her about having fun with Nika while he was chained up, was the same downcast face when she talks to Nika about it to apologise. She looks down when her mom wonders if this is the NIka from the rumour, she gets upset when NIa mentions the rumour. I feel she is easily pushed around.
For all the things I dislike about Bella, she does actually have a mostly fair view of people. She didn't say anything bad about Robin, but Kate.... and maybe the difference is that Robin doesn't fight against more dominant people like Bella.
If you think of all the scenes where Robin talks, most often she is just trying to make people comfortable, almost as is she owes them something. I think she has very low self-esteem. You can see it in her face when any conflict is mentioned around her - her instinct is to flee or submit.
Edit: and no one in the thread really credits her for going to see if Nika was okay if the eraser incident happens. Given how easily she gets upset, and that Sasha might carry around meds to help Robin, it might be quite a big effort for her to go to see in Nika's okay and help him. Her instinct there was better than anyone else in the class.
