In the Seven Deadly Sins, starting with Fred, as each person emerged, they all asked about the disappearance of Enfei's mount.
After being asked two or three times, she grew a bit impatient. Finally, when the last few people arrived in the Material Realm and looked at her, she shouted with a dark face, "Don't ask me about the mount! Are you people annoying or what, asking the same question over and over!"
The others, seeing she was in a bad mood, couldn't be bothered to provoke her further and instead turned to ask the ones in front about the matter. Though Enfei didn't say, the other six quickly understood what happened.
Gried had fought with Guding before and nearly killed him. When Prometheus rescued Guding, he also used the Karmic Fire. Now, years later, it's no surprise Guding has mastered the Karmic Fire.
