Everyone has dismissed Citrus Fruit's bandage as an injury. Even pr0gram dismissed it as an injury until they overheard her talking with Targety*, being the nosy pro they are. Once TG left the room, pr0gram entered through the wall. CF immediately freaked out, nervous that pr0gram was going to reveal the secret. And so pr0gram promised (even pinkie promised) not to reveal the secret. And thus, CF reluctantly gave pr0gram permission to see what was under the bandage. So what is under the bandage? I'm only going to reveal that once the time comes.
*Targety is Citrus Fruit's best (and only) friend. And to answer why, we need to A: Explain the other part of TG and B: Talk about parallel universes.
