So I rewatched the episode last night where Tigra is stuck in a cave that's rapi aging him and he needs Cheeyara to save him. It made me realize two things.
1. How did Panthro get there the same time as Cheetara? They both seemed more or less the same distance away when they saw the Swords call.
2. Isn't the Sword of Omens a rather inefficient calling beacon? Any time Lion'O uses it, every Thundercat able to answer the call will answer the call regardless of how important what they're doing is. Everyone gets there and it's like, "Thanks for coming, but I really only needed Cheetara." Panthro would be like, "Okay, fine. Now you can go all the way back and get the fuel that powers our defense system."
