Connor gave a little smile as Kon figured himself out. A spinny room? Poor thing. He wondered briefly if they'd overestimated the amount of tranquilizer he'd need, but he knew Abby. She knew what she was doing. He trusted her with his life and with the life of his best friend. He'd given her all the information on Kon's physiology as he possibly could and she'd worked with it. He'd be disoriented, but he'd be fine. It wasn't just the medicine the boy was trying to come down from, after all.
By this point, he didn't even get worried when he saw Kon falter at the word. It was taking time to re-acclimate himself and he knew it would be a bit before he was truly the Kon that Connor knew and, if he let himself admit it, loved. "Yep, Krypto the dog. We're going to make sure no one's going to hurt you." He placed a hand against Kon's shoulder, urging him to meet his eyes. "No one. You're safe here, Kon. I promise you that."
It might have been an empty promise, but he really hoped not. The tranquilizer wasn't deadly, not like the kryptonite. It wouldn't cause him pain. He'd be okay from it, so even if they did have to take him down again, even if Connor did lose this bit of contact, his friend wouldn't be hurt. He'd sleep it off, with any luck.
"You know nothing I give you for it's going to help," Connor pointed out, then took his friend by the arm, urging him to the kitchen table. "Come on. Why don't we see if some food helps that head, hmm?"
It was a bit like taking care of a small child. Or a mental patient. Or a young mental patient. But he was okay with that. Whatever would help his best friend.
