"Don't think I'm doing this because Bruce told me to do it, but … uhh …" Tony seemed to fidget for a little bit before saying, " … I placed a GPS tracker on your glasses."
"Excuse me?" Harry had heard it alright, but he wanted Tony to repeat it just to be certain.
"Well, it's not like it made much of a difference. I can't track you anymore anyway."
"Another surprise?" Harry pulled his glasses off and cast Immobilus on it to make sure he couldn't be tracked at all. "Why now to tell me this?"
"I mean, you were popping around all over the place and you were practically a stranger," Tony tried to excuse his actions. "You also were new to this universe."
Harry scowled in response. He could almost understand Tony's reasons if the tracking didn't anger him so much. "Did Bruce promise to tell me if you didn't? He did, didn't he? Merlin! Don't do it again or I'll – I don't know – make you vomit slugs."
"You can do that?" Tony asked, stunned. It didn't last long though because the next thing he said was, "Huh, I wonder how that works."
Harry growled in frustration. Tony was not taking the threat as seriously as he had wanted.
