Thor nodded to Riza, silently letting her know that she could come and join them. Riza came up to the brothers and noticed Loki's skin looking pale. She also noticed his teary face. She looked rather worried for Loki, seeing him still upset. He had either been crying for a while or just recently. But it didnt really explain why he was becoming so pale. "Will Loki be alright?" She asked Thor who looked concerned himself. "He is just going through a hard time with all that has happened. Comfort and company should help him through his troubled time." 
The young Stark nodded slowly in understanding. This was a hard time for the god and right now, he was going to need as much help as possible. Touching his forehead softly with the back of his hand, she wanted to check to see if the god of mischief was running a fever. She couldnt tell but with Loki crying as much as he probably was, crying could be draining his energy. Either way, she was worried.
