Joan and Erika saw David come up out of the hole as the Professor lectured at May angrily, still holding onto her ear. Erika tried to get their attention, but David had already made it up, and unsheathed his sword, shouting at the Professor. May face palmed herself while the Professor stared at David wide eyed, letting go of May's ear. Erika had bursted out laughing at the fact that David had called the well renowned ex-archeaolgist, now college professor, an old cretin. Joan asked May, "May…Who is this guy?" 
She answered "He's the zombie I mentioned,"
Joan chuckled "He doesn't look like a zombie,"
May commented "He was in a glass coffin. A. Glass. Coffin. Doesn't that scream zombie to anyone else?"
Erika laughed, "Well, he sucks as a zombie. He's trying to use a sword, instead of trying to devour someone's brains,"

The professor recovered from his shock, and he glared at David, sternly telling him, "Young man! You are very close to the college campus, I would suggest you put away your weapon!"
May figured that David wasn't going to listen to him as the Professor pressed "WELL?!"
May said to David "Just do as he says,"
