Jason gets triggered by certain words into a soldier the league trained, and Damian tries to figure out if Jason is ظل(zala = shadow, translated by google) his "babysitter" and bodyguard from his childhood.
There is a situation where Damian has to battle someone and is forced to use a single weapon. After thinking about his odds, he chose ظل, because either he is right or wrong (of course, he is right)
Jason is frozen in his spot when Damian starts to say something in arabic. "عليك أن تخدم وتحمي رأس الشيطان. يجب أن تأخذ أنفاسك الأخيرة أثناء حمايتي. أنت جنديي الذي سوف يستمع وينفذ أوامري"
("You shall serve and protect the demon head. Your last breath shall be taken while protecting me. You're my soldier, who will listen and act to my orders", translated by google again).
After Damian finishes, you can see how his opponent just stands there and laughs until blood starts to run out of his mouth because he has a katana sticking out of his stomach. He spits blood and dies and bla bla bla, irrelevant.
The opponent falls to the ground and reveals Jason standing there, looking catatonic, no shine in his eyes, and Damian knew he was right.
However, he doesn't know how to "end" Jasons "soldiers' mode," which causes chaos afterward.
Damian is in school, he will see Jason sitting in a three in a league uniform (Jon is freaked out by it)
Damian is on a mission with the Titans? Well, he ain't going alone
However, Jason freaks everyone out, even his family. It seems like he doesn't need anything except training and Damians' presence.
Jason cooked a feast once, only for Damian, and when Tim tries to take something, he almost loses a hand (Jason did it only for a thread, if he wanted to he would have cut Tim's hand off).
It frustrates Damian so much after a while that he asks Bruce if his mother could come over (of course, Bruce says yes because he wants his son back).
When Talia arrives and she sees the state Jason is in, she talks with Jason on Arabic about "his state".
(Like, "Who are you?" "Your Soldier, my queen", "Who told you to protect Your Prince?" "My Prince himself requested my protection")
And of course, Talia gets Jason to snap out somehow (he pretends to have no memories about this time, but he knows everything).
(I didn't think further, but if you have any ideas, please let me know)
