In my Secret of NIMH AU; "Mrs. Brisby & the Bund of NIMH", Racso is always the sensitive topic for Jenner. Ever since hearing his son's death (with only thing intact was a military cap he gave to little Racso before), he went obsessed with obtaining strength and power. Because, he blamed his powerlessness for unable to protect his son.

Through every time he gaze at the military cap, he'd daze to dream what is like if his son was alive and in the colony bund with him. Little Racso would grow into fine young boy, always following him to the training ground. Racso could have been going to school like other children. Jenner would watch proudly on things his son would be good at. A little boy would need a mother, so sure, Jenner could find good mother figure for him. They'd have been happy........ if it weren't for damn NIMH, if it weren't for cruelest state of men done to his son.... if he could find a way to bring his son back to life.... and if NICODEMUS DID NOT "RUIN" EVERYTHING HE PLAN TO DO.

"Once rid of Nicodemus, the plan will die... we can stay here as long as we like"

"He wanted to destroy EVERYTHING!"

"I've learned this much; TAKE WHAT YOU CAN... WHEN YOU CAN." - Jenner
