This was a great episode, loved the Drifter although I thought he'd be a villain in disguise with the way he was putting Lion-O down at the beginning(Good thing he wasn't). I thought it was kind of silly how Lionel just suddenly had the skills to take down the Duelist after having a talk with the Drifter but the fact is that as a prince, he was trained in combat and all he had to do was clear his mind and use those skills. I also thought it was strange how the Drifter took the Duelist down with a piece of willow or whatever that was; but it was cool because the lesson was that he focused on using his inner strength, not his weapon.
Something I enjoyed and was waiting to see was how the animals in the city treated Lion-O and his Thunderian heritage. The Thundercats are just like all of the other animals now that their empire is gone, and I'm sure that's going to come into play more in later episodes. I also liked the mixture of the different species and I even saw a Parrot in the crowd, pretty unexpected.
Speaking of later episodes, now that the Drifter has taken the Duelist's stolen blades and is travelling to return them to their rightful owners, I hope that he and the Thundercats will cross paths again in the future. He's too much of a great ally to just never see again imo and he might even have the previous owners of the swords as his teammates, that would be cool to see. Could we also be seeing the Duelist again down the line? His reputation and power was basically taken from him by Lion-O, so he might somehow align himself with Mumm-Ra for vengeance or just go after the prince on his own.
With Thundercats, A:EMH, Young Justice, and the new Avatar coming out I feel like a kid in a candy shop.
