This week on Numbers (Fridays, 10 pm/ET), the CBS drama marks its 100th-episode milestone with a case that harkens back to Day 1, when a serial rapist vexed Don and Charlie. Original cast member Alimi Ballard, who week in and week out offers formidable back-up as Agent David Sinclair, gave TVGuide.com a look at the very creepy case to come, raved about the Fonz's utter coolness, and teased a season finale that will leave fans - and a very important something - hanging.
The Creepiness Adds Up in Episode 100 Spoiler Warning: Potential spoilers for episode 5.21 - 5.23. He tried to be vague, but just to be on the safe side... I thought I'd let you know. :)
