Jason

Jason is a former best friend with Gary. He is seen in Season One, episode one. In the first episode, Gary takes him to his house, where his nan is visiting them. Jason didn't seem interested in Gary's sister who flirtaciously smiled at him, but was instantly smitten when he caught sight of "nan". Since that episode, Jason had been trying to hit on her and never let her out of his sight. He even walked her to the toilet and made a move on her in the process ("Oh, sorry, I thought that was your elbow!").
