Steve knocked gently at the door to the guest room before entering. He didn't expect either occupant to be sleeping - Bucky would have woken immediately when Harleen knocked at the front door, and Ariel had been up earlier. But the knock was just polite, even if the apartment was his. He opened the door and stepped in, looking to his charges.
"Ariel, there's a doctor here. Her name is Harleen Quinzel. She wants to talk to you about that happened at Arkham, so that you won't have to go to court later."
His voice softened a bit. "She helped us find you. She's a friend."
