I'm looking for a fic.
Tony meets the Ancient One and gives her his phone number to call for whatever reason and she pulls a cell phone out of her robe pocket. The only problem is, she doesn't actually own a phone, and reveals that Tony subconsciously (magically) and spontaneously created a phone for her to call him on.
I don't remember if there's any actual pairing but if there is then I want to say it's IronStrange?
Thanks in advance!
(ETA: typically, as soon as I post about looking for 2 fics, I find the first one lol. Still after this one, though!)
