About the character you asked.
On the last issue, Peter Octopus was revolted that Peter Spider didn't even finished college, as being a doctor is very important to him. So he signed up to finish his course and he signed up for a very difficult chemistry class. This girl is a private tutor who kept buggering him to give him private lessons, but as we saw on this edition, he really didn't need them and he just stopped there to say that.
Now, What I find interesting is the possibility of she being a love interest of him, not a borrowed Peter Parker girlfriend, but someone Otto actually likes.
She's definitely going to be that, Slott previewed a few of the Ramos pages a week or two back and it looks like that's where he's taking it.
