It was a quiet night in the UA dorms, and you were playing Mario Kart with Kaminari when your twin brother, Lincoln, woke up panicking and crying, which you've never seen him do

Lincoln was hyperventilating and clutching his stuffed rabbit, definitely a panic attack. What do you do

(A little bit of context. Lincoln was heavily beaten up by his sisters other than you and Lily, which sent him to the hospital and wind up with syngenesophobia. He came to UA with you for safety)
