Thad is one of my favorite nerds. His lisp makes me laugh at times, and he seems to be a bit less cowardly than the other nerds, for example when he rushes to your help in the mission Character Sheets when fighting the bully at the autoshop, yelling "I'll help you in you battle againtht evil!". However he gives up easily when you have to fight him to get the code to the observatory. But I still like him, he's good with fabricating weapons. He broke a yardstick over Peanut's head and got away with it, and according to Troy he once made a fricking grenade out of an eraser! That's pretty badass.
If he can make a grenade out of an eraser, than he's pretty badass for a nerd. I'll give him that. -TTG (January 12, 2015; 7:29 PM EST)
