If Rex were with her, he would be concerned. He'd watch over her closely, making sure no one took advantage of her in her drunken state. He might also try to find a way to help her sober up, like getting her some water or finding a quiet place for her to rest. Meanwhile, other characters who don't know her well might misjudge her and think she's just a reckless individual, but those who are her true friends would understand that it was an accidental situation and support her through it.
Her best friend might be very concerned and protective. They would try to keep her from doing anything too crazy while drunk. For example, if she tries to walk into traffic, they'd stop her.
Anakin, if he's in the story, would likely be very protective. He might rush to her side immediately, using his skills to try and heal her or at least stop the bleeding. His reaction could be full of anger towards the cause of her injury, vowing revenge.
Fang would probably be protective. He has always been close to Maximum Ride, and with her pregnant, he would be on high alert to keep her safe from any threats. Iggy might be a bit more practical, helping to set up a safe place for her to stay during the pregnancy. Nudge would be excited and full of questions, constantly asking about the baby.
Well, the plot could involve Ahsoka getting drunk at a celebration on some new planet she's visiting. As she gets drunk, she starts to recall memories from her past, both good and bad. This could lead to her having deep conversations with those around her, like sharing her thoughts on the Jedi Order in a more unfiltered way than she usually would. Maybe she even stumbles upon a mystery or a secret that she wouldn't have noticed if she were sober.
Akane would likely be very confused and worried. She might initially think Ranma is playing a trick on her, but as she realizes it's real amnesia, she would try to help him remember things. She could become extra protective of him. Genma, on the other hand, would probably be frustrated. He'd be worried about how this will affect Ranma's martial arts progress and his ability to uphold the family honor.
Starfire would be overjoyed. She's always been the emotional and positive one. She would probably throw a huge celebration for them, with lots of alien delicacies and bright decorations. She might also give them some advice about love based on her own experiences with Robin.
Some Jedi might be shocked. The Jedi Order has strict rules about attachments, so a kiss between two Jedi would be seen as a deviation from those rules. They might initially be disapproving, especially the more traditional Jedi.
He might be more open and affectionate with Sam and Dean. Usually reserved, the alcohol could make him more likely to give hugs or say things like 'You two are truly my best friends on Earth' in a slurred but sincere way.
Arthur might be initially shocked and confused. He's used to Merlin being in control. But then he might find it quite hilarious and start teasing Merlin about it.
Sakura might be initially frustrated. She's used to Sasuke being in control, so seeing him drunk could be a bit of a shock. But then she'd probably feel a sense of protectiveness and try to sober him up.
