(This idea was inspired by this video ^^)

After Red Leader (aka Tord) discovered Gray Leader (aka Kitti) was his biological son, because of this, he thought he could try parenting Gray Leader (or rather more like try taking Gray Army into Red Army, wanting his own Army to grow more powerful).
That plan obviously didn't work since 1. Gray Leader refuses to knowledge that Red leader is his father since he hate him and 2. He already have someone as his father figure

(Incase no ones knows what AU this is from. It's Dark Time AU, I created it)
