30(Crossover)

This is basically the Au for Rejection Letter 164.

It follows The Black Phone canon except that the other boys did not die but were in a coma(the specific reason why the Grabber did not actually kill them is up to the writer) and that is why he could communicate with them.

Once Finey kills the Grabber and the boys are found, they all stay in the hospital for some time but for their protection and to not able to deal with the town's gossip and pity it is decided that the boys should be moved to somewhere else(be it with a family member or a close friend).

Finney is taken in by his Aunt Denise Harrington(nee Adler) and Uncle Daniel 'Danny' Harrington were he becomes Steve Harrington(of course while he becomes a popular, he does actually bully anyone and tries to make the others not do it too which does not really work).

Stranger Things canon happens except that Finney breaks up with Nacy after the 'cheating' incident and while they are friends they aren't really that close plus a few characters that die will live(example Billy and Eddie) as Finney gets the ghosts of Henry and Brenner's victims to help them.

The kids do not find out about Finney's powers or Gwen until the last fight with Vecna but Finney still does not tell them everything just that he found out his powers by accident and that it was inherited from his mother.

Also, The Black Phone 2 does happen between Finney 1st year and 2nd year of high school.

Now about if Finney and the Ghost Boys meet again...they do, the boys slowly find each other until only Finney is missing but it takes some time to find him(as information about where the boys were was hidden and locked).

They needed Gwen's help, who still lived in Denver with Terrance and was dating Ernesto, to find out that Finney was in Hawkins and after she gave them his number they called him.

Finney did not really having anything locking him in Hawkins as the kids and Robin had already finished high school and were in college or moving to college so he decided to go back to Denver to meet his boys once again.

Things happen and they all start a relationship that leads to marriage(with all of them deciding to hypefen Bruce and Robin's last name and have it as all of their last name).

How do the kids, Robin, etc react when they find out or anything else is completely up to the writer.
