Isn't it great that Erza couldn't requip? If she could she'd just have destroyed a few of her armours only to end up in the flame pants.

And yes, the thing with the keys being given back without them being taken was stupid. If Virgo had taken them when she switched Lucy into the bikini, she'd surely have taken the black key and her whip as well, so that couldn't have been it either.
