Cam would be in a state of worry but also in her role as the boss, trying to keep things in order. She would be making sure Brennan gets the best medical treatment available at the Jeffersonian. All the characters would feel a sense of loss and unease, as Brennan is such an important part of their team and their lives.
Twilight Sparkle would likely be extremely worried. Since she raised Spike, she would feel a deep sense of guilt, as if she failed to protect him. She might even blame herself for putting Spike in a situation where he could get hurt in the first place. She would probably rush to find a way to heal him, using all of her magic knowledge.
The whole team would experience a range of emotions. JJ would be concerned not only for Morgan but also for how the team is handling it. She might be the one to try and comfort Garcia. Prentiss would be angry. Angry at the shooter and also at the situation. She would be determined to bring the person to justice. As for Morgan himself, he could be feeling a mix of pain, fear, and determination not to let this be the end. He would be thinking about how he can get back to the team as soon as possible.
They would feel a mix of guilt and anger. Guilt because they might think they could have prevented his injury. Anger towards the person or situation that caused it. Eric would be especially emotional, as he and Ryan are close friends. They would all rally around Ryan, and this would strengthen their bond as a team.
The other characters would likely be very worried. Stella might be especially emotional as she's one of Flora's closest friends. She could be seen crying and constantly hovering around Flora, trying to make her feel better. Musa would probably be quiet but deeply affected, using her music to try and soothe Flora's pain in a way.
One possible storyline could be that Brennan's friends and colleagues at the Jeffersonian are in a race against time to find the shooter while she is in critical condition in the hospital. They follow every lead, from her past cases to any personal enemies she might have made.
Simon might be in a bit of a panic. Since he's her friend and also not as used to the dangerous situations as the other Shadowhunters. He'd try to do whatever he can to help, like getting help from more experienced Shadowhunters or trying to comfort Clary while she's in pain.
One possible storyline could be that Brennan is injured during an excavation. Maybe a cave - in occurs and she gets trapped under some rubble. Her team then has to race against time to save her while she struggles with her injuries. Another could be that she is attacked while working late at the Jeffersonian. This would not only lead to her physical hurt but also psychological trauma as she tries to figure out who did it and why.
The other characters' reactions can vary. Pixal, if she's around, would use her technological knowledge to see if there are any internal damages to Jay, especially if it's related to his electrical components. The villagers of Ninjago might also show their support. They could bring food or offer shelter for Jay to recover. The reaction of the villains would depend on the situation. Some might see it as an opportunity to finish Jay off, while others might be impressed by his courage in getting hurt while fighting them.
Maybe it's a jealous rival in the forensic science field. They see Brennan as a threat to their own reputation and success, so they arrange for her to be shot to get her out of the way.
One common theme is the adjustment to motherhood. It shows Brennan trying to balance her scientific mind with the new emotions and responsibilities that come with pregnancy and impending motherhood.
