Thor hugged Loki when he had come to hug the thunder god. He had noticed that the god of mischief had calmed down extremely to see he had control over his joutun form once again and was back to the way he had always known him. Riza had had handed Captain Rogers his shield of which he took it and attached it to his arm and thanking her before the young Stark looked at Tony to see that it looked bad. She looked to Thor with concern. Thor had looked to everyone to see Tony in pain. He too looked concerned before they all started off toward Riza and Loki's entrance through the fence, then out into the rest of the barren ice covered realm of Joutunhiem. 
Within ten yards from the facility, the alarms had started going off as Riza basically predicted. Riza decided to get into her suit before continuing on, staying close to Tony as did his suit. Within being fifty yards out, Thor stopped as did Steve and Riza. He looked around, thinking no one else was around and they were safe. "Heimdall! Heimdall open the Bi-Frost!" Thor shouted. But no answer Thor had waited a few more moments before Shouting for Heimdall once again. Riza looked confused before looking to Thor. "Is something wrong?" She asked Thor. The thunder god looked at her before looking around. "He's not opening the Bi-Frost. I am guessing that something is close and that he cannot risk Asgard being attacked with something nearby." He turned his attention to Loki. "This is where you lead. But watch out." Looking to everyone. "Joutunheim is most dangerous. There are frost giants that will kill us. Do not let them touch you." Thor warned.
