I went into my trash and found the thread. I didn't see a button to move them out of the trash. In the drop-down menu I found "report spam" "report not spam". I hit "report not spam", and an android toast said "one message has been marked as not spam", and the entire thread moved out of my trash and back into my email.

I might be able to take this thread to authorities and researchers to secure my email!

My Gmail client now says 55 messages in this thread have been deleted. It gives me a button to view them. Each one says "this messages has been deleted" at the top when viewed. Im not at this time certain how to undelete them.
