Thor pulled his hand away from Loki so he wouldn't hurt his brother as he clenched his fist. He knew that if they met up with his friends that he would need to defend Loki, but it hurt to hear it. He didn't want there to be problems. He just wanted to stop the fighting and work on protecting his brother.
"We were hoping that, since so many do want to attempt to harm my brother, hiding him here would be perfect. Thanos would assume Loki would be in Asgard first and, we hope, will look here last." Thor glanced to Loki. "Perhaps we will go to another realm after he has looked through it, but he will come here whether we are still hiding or not."
