"My ANTIQUE MICROWAVE!"
Nero had paid good credits for that 20th century artifact. He was going to turn it into a hobby project or something for use during his spare time. And now this complete stranger had come along to construct... who-knows-what!
"What kind of zapcrap you trying to pull?! Gimme back my stuff, you scantily clad iconoclast!"
"It wouldn't be of any use for you in its current state."
The woman ignores his demand as she continues to fiddle with the newly- created device. She aims what appears to be akin to a classic model of smartphone from the 21st century at it, double checking a few things on the screen before she nods a few times.
"I won't be able to program it with this model of tomephone anyways, and without a sufficient aether source—" She's completely engrossed in her little tech project, tapping away on the touch screen before raising her head to look around the place.
"You wouldn't happen to have an analogue monitor among those relics of yours, would you? I can solder a connection but without an analogue signal it won't go very far."
Without waiting for a response, she was already beginning to pick through Nero's belongings. "Your microwave is the key component to what will become the core of a portable time machine, but right now it'll likely just zap you into a wall, or rearrange your bones into jelly due to the pressure. That is to say, don't touch it until I'm done here."
