Greg didn't say anything to them. He only laughed, but even this was grating on the ears. It caused many people to speak out in complaint about him.
Loki shook his head when he saw this and said, "It seems that whatever this guy does will come out as irritating."
After that, many people still questioned Loki's decision to follow Greg, and Greg made promises about how this was a good thing and how he would make sure that no one would regret following him.
Loki kept speaking up for Greg, but he didn't believe a single promise that Greg made. This was because he didn't trust Greg at all. He has had enough experiences with Greg to know that Greg can be more dangerous as an ally than an enemy.
Despite knowing this, he still has his mind set on going with Greg to attack the nearest fortress city because he is confident of handling Greg. Instead of counting on Greg, he is counting on his own power.
