This is an amazing story! I've read other ST fics where the other kids have powers and even one or two where Will develops them b/c of the upside down but this is great in tying the pieces together. When he and El figure out that they are amplifying each other it's going to be fun to read. And Erika as his go-to help is BRILLIANT!

Erica actually being nice with someone is a welcome change. Her theory is probably not far off

I think you’ve got some good ideas and good characterizations in this fic. I like that you show both Will and El struggling with grief. It is a little hard to follow sometimes. Whenever there’s a new speaker, there should be a new paragraph or if you change a character point of view, there should be a new paragraph. Also, if you write it and set it aside for a day or two before proofreading it, that’ll help. If you do that, I think you’ll get a lot more reviews because your ideas are good, it’s just hard to follow. Like when El wanted to talk to Mike on the phone, I wasn’t sure if Jonathan was talking to Nancy or if Will was actually taking to Mike at that moment.

I really like your style of writing in this! The characters feel very true to the show and incredibly human- you've done a great job at capturing them. I'm eager to see how Will's powers and relationship to El turns out.
