Purple: WHY.. WHY DID YOU HURT THE SNACK MAKER?!
Red: .......

couldn't think of something for him to say that would be too out of character
Jen is too small for favor in the tallest, until she starts making/bringing them snacks. With her title of 'Snack Maker' she has found much favor in them.

Though Red does beat the crap out of Purple, I think deep down he cares for his feelings.... a teensy bit... specially if it's about something they both agree on... LIKE SNACKS!
And so red is understanding Purples feelings and is already working on revenge plan for whoever has thus injured the Snack Maker.
