Andrew greeted Emaliene who was accompanying them and finally approached Biacko. In Andrew's eyes, which could see the aura, he could immediately identify the dragons.
Since the dragons had treated him with so much respect starting with Lugia and Crhono, Andrew would not be disrespectful to them unless they offended him, so he greeted him with the same seriousness as he did with Emaliene and Lugia.
The other demigods who had just been gloating that this time Andrew had come out to greet them in person put on bitter expressions. In the previous meeting when Andrew did not receive them, they felt bitter.
Now that they saw him receiving them, they believed that Andrew had learned his lesson and was now giving them the respect they deserved, they immediately understood that this was not the case.
