Hmm... Liam really should listen to himself. Six months isn't a very long time to get over a man who's had such a powerful inpact on him. And still has.
His reactions are not a sign of moving on and finding a new love interest. He has to be careful not to lead Nathan on. That would be kind of shitty. At the same time, he's been open about his break up and Nathan as a grown man should know about rebound syndrome... Still, go easy on the flirting, Liam. Also, we don't know what Alek is planning...
