So the truth is that from the moment Gemma heard the first rumours that this was a thing, she knew she was going to be there. She knew she was going to be there dressed in something skimpy and white and streaked in body paint from cheekbones to feet—green, it turned out, chosen completely at whim in the moment and not for any particular effect.

If Gemma has a superpower—and she doesn't count her meagre magic because that's not particularly super at all—it's always knowing where the party is. She spins in the lights and dances to whatever music she's nearest to and occasionally flashes a smile at someone she's sliding, spinning or grooving past, around or, occasionally, into.
