“We ready, Jarvis?”
“As ready as can be expected, sir. Standing by in case of emergency.” Indeed, Jarvis was standing near a more-or-less vacant worktop, a safe(-ish) distance away.
“Great. You, Butterfingers, you both know what to do.” The armature bots whirred quietly, one holding a camera, the other a fire extinguisher.

Piece by piece, it skittered through the air, attaching and interlinking, and occasionally knocking into things, and occasionally needing a bit of help.

“The homing system requires a few final calibrations, but all other systems are within normal parameters. I would suggest—”
“The window, if you’d be so kind.”
Jarvis sighed and rolled his eyes. “Of course, you’re going to test it from this high up. Forgive me for daring to hope otherwise.”

“You’re forgiven.” Tony gestured expectantly towards one of the windows, and it slid downwards and out of the way.
“Cheer up, worrywart! Just a little test flight. You’ll be with me the whole time.”
“Consider me comforted.”
