Hm. She built the leg herself, so she wouldn't need it inspected by somepony else. The curiosity angle might work, but I don't know if there's much to keep her there.

Given Wrench's personality, the scientific thing might be the best angle.

Well I don't mean inspect as in check to see it was built right, I meant more that he would be curious about it and probably wouldn't bother asking permission before looking it over. Anyways, the science thing sounds like the best bet.

Ah. Well, he can still look it over anyways. I kinda have an interesting idea if we do the whole anto-magic-surge angle, since it would be of interest to both of them, just for different reasons.
