The answer to the last question is Artemis and Apollo. Here is chapter 3.
Barry POV:
I am running, running fast. I am running back to S.T.A.R. Labs as fast as I can because I can feel the effects of the poison in my lungs. I make it to S.T.A.R. Labs and collapse in the Cortex.

"Can't......breath."

I see Dr. Wells and Cisco.

"Get the crash cart!"

I see Cisco run off. Then I blackout.

Everything is fuzzy.

"What happened? How long was I out?"

"You were out for about a day. The poison caused a depletion of oxygen in your lungs."

I look up and see Caitlin.

"I need to get to the station."

"Barry, you're not leaving yet."

"Fine Cait."

I see her walk off.

This was a really short chapter. I am copying this story from my google docs right now so once I start writing chapters on Wattpad they will be longer. See you next chapter my special snowflakes. Random trivia question of the chapter:

Who is Nico Di'Angelo's full sister?
