It says in all about soap magazine that in febuary someone decides to come back to hollyoaks to seek revenge on sam and russle and also has dire intentions for nicole! i presume this to be andy returning to get his own back on sam and russ and by doing this he intends to rape nicoel,after all he did say quietly to himself when with her "you'll keep." this would be the ultimate revenege on the brothers wouldnt it i cant think of anything else it could mean can you?
