If Ra's has control over the thing in Damian's spine. Bruce'd be livid! Just imagine Tim working his hardest to deactivate or take it out. While Bruce is just holding really weak, tired, and in pain Damian. Damian's screaming & crying in pain kill Bruce and Alfred's heart the most. Their baby is in pain! Damian keeps apologizing for hitting them etc because he has no control over his body. Damian passed out cold from all the pain & suffering. Probably need to be hooked up on IV too :(
Then what if Damian's not supposed to be able to walk without the thing inside controlling him? The girls are working with Tim to deactivate it but when they realize this, I think Barbara will be hit them most. She'd do anything for Damian to walk cuz he's only 13! But Damian wants it out from his body. He'll train to walk for a long time while alternating with wheelchair too. Dad & Dad-lite will be the happiest when they see Dami walking again tho he fell on his 3rd or 4th steps
Aw, Damian would feel so guilty, even though absolutely none of it is his fault. And he’d try to hide the pain of fighting the machines, but Bruce, for once, would see right through it. Hold Damian and tell him to let it out, he doesn’t need to hide anything anymore. So Damian does. He hates it, hates being so weak, but he cries in his father’s arms. Clings and squeezes his hand when the pain is at its worst.
And while Dick is off fighting Ra’s, he’ll have his communicator on the whole time, will hear all of Damian’s pain and anguish, and Tim’s attempts to fix everything. It’ll fuel him to move as fast as he can, and save his baby.
Barbara would definitely be hit the hardest if the implants cause Damian to be paralyzed. It might make her relive/think about how she became paralyzed too, and that’s not good for anyone.
But the family would already be working on ways to fix it, so she goes another route - she helps Damian with the paralyzation. Talks with him about it, makes sure his emotions are okay. Basically give him all the help she might not have had herself.
And she’s just as thrilled as dad and dad-lite if Damian regains his abilities. I feel like she and Damian would have a new understanding/friendship then, so if he does regain the ability, he’d go to her first for any sort of affection or hugs or the like, even before Bruce or Dick.
