"Because you could do so much better than him!" Jack exploded the words out. He didn't need to know Frank to know that that was true. He could just tell! This Frank guy was a prat! And a knob head! And a lot of other not good things!
"You could have loads of guys throwing themselves at you," he muttered, although he didn't particularly like that idea either. They would probably be knob heads as well. Andrew was just too sweet, too naive, to see the jerkfaces standing before him.
And then he made a flailing noise as Frank PUT HIS ARMS AROUND Andrew! Touching his best mate! Steering him away! "Don't call him pet you knob head!" he shouted, and really, Andrew shouldn't have been worried about making a scene, because everyone was staring at Jack, who was really putting on a show.
Hw glowered at Frank - and then when the bloke turned to steer Andrew away, he picked up a piece of discarded scone off a plate nearby and winged it at Frank. He felt a bit of satisfaction when it bounced off the back of his head.
