Theodora + Avery seems like a match made in heaven.
Profile
I mean, Avery broadcasts her emotions more strongly than other people, and right now her emotions are full of stuff like 'mom and dad threw me away', 'what if people are right about my powers and I'm wrong' and 'the whole world is out to get me'. She'd be like an Olive Garden never-ending pasta-bowl of powerful sad emotion. Plus she's a great drama bomb to huck at others, since she has the tendency to dig up (read: accidentally create) dark secrets about people through her 'investigations'. I think Theodora and her would have some good chemistry (and by good chemistry I of course mean the two would be a good source of endless drama).
And hey! Maybe someday they'll both learn to live with and appreciate their powers and become actually good friends!
