A phenomenal ending that closes all that needs to be concluded between Vash and Knives, and the safety of humanity's future. Knives brings out his full mastery of their mysterious power as Plants, leaving Vash to find ways to counter it with his own. I certainly wish there was more to the fight than them only standing at one point, but I feel like that stillness also serves in showcasing their opposing dynamic at a standstill until Vash comes up with a solution. Overall, it's still a great ending!
