Florrie's run was immediately following on the disastrous attempt that Fabian and Remus had aborted after Remus had pounded into one of the flaming hoops. After she'd taken care of them, she put on her gloves and goggles and mounted up for her own test.
It was no surprise that the damaged ring had collapsed midway through Florrie's run and that she had a net spell at the ready, of the sort the ambulators used to protect injured people from wreckage, and that she was able to complete her run even so. It did mean her time was below par, and she shot an annoyed look at Merc about the whole thing.
