Ah, just like the good old days. Ali would say something witty and get Ever flustered, she would cuff him on the back of the head and admonish him, and he'd turn it around on her anyway. In this case "You are so weird" was countered with "And you love it. What's that make you?" Accompany with smug, cocky grin for maximum effect.
He followed her down the halls, feeling generally smug and victorious and no longer making much effort to remember which way was which. He'd just wing it next time and if he got lost (which he would never admit to anyone, ever) he'd just stumble around until he got lucky. Easy. "So this party your new beau's throwing," he said after a minute or so of silence. He didn't like silence much. "Where's it at? What time?"
