Looking at the OP again, blink and you miss it, but I thought Frosch being on Minerva's shoulder was cute, than again anything Frosch does is cute and only Asuka beats Frosch in cuteness, but giving Minerva with exceeds, she has taking as many exceed hostage as humans, this is a step in the right direction for her.

Though I am sure the Rogue x Minerva shippers are going to find reason to think that is a sign.
