I like both Spiral and Nikki. I admit that Spiral was probably feeling moody after being rejected by Aisleyne. Who knows, now that they've both got some discomfort with Aisleyne, they might become friends lol - even though Aisleyne picked him he's obviously taken everything the wrong way. About Spiral shouting at Nikki though, he's just being like Mikey in that respect, they seem to be the only two who won't put up with Nikki's childishness all the time. Either way, though, they sort it out, and the Nikki/Spiral thing wasn't like the Spiral/Jayne shouting thing in the middle of the night - it's all sorted now anyway!
But bear in mind what I said about Spiral and Nikki perhaps becoming good friends over their shared discomfort with Aisleyne!
