I like it, but some minor issues of not capitalising the begining of a sentence or forgetting to put a full stop on the last two paragraphs.
It's good could use a once over to catch minor mistakes but good, storywise I wonder if Taylor actually has any powers, sure a guy from our world is in her head ok, but how does that help fight something like an Endbringer?

Why Medhall's hospital, and not Brockton Bay General? Brockton Bay General is the hospital Panacea volunteers at, and the main hospital for the city.

Actually... In canon there's never shown to even BE a Medhall Hospital. Medhall is a medical supply company, they make equipment and medications. Medical supply companies don't typically have a hospital of their own.

Hmm, you know, I think now I truly believe that Brockten Bay is THE shithole.

Excellent start. A proactive Self Insert who solves the biggest issue in the first act. I am really interested to see what you would do next. Watched.

I am seriously looking forward to this story. The Ron Weasly one was kick ass so i have high hopes.

Eh if you don't think the story has to make some sense it could be readable.

Snazzy, some real problem solving here.
Mm feels good.

Very strange... nah, I don't think it's readable, sorry.

I think I saw a few extra quote marks but other wise an interesting start lets see where it goes

Now this looks like it's gonna be a fun ride.
