Except, I didn't like Ash's reaction when Roggenrola first appeared. It seemed rather obvious that Roggenrola needed help, and Cilan at the least noticed this.
I also didn't find the title to be particularly accurate, or exact, rather... even though Ash at the beginning wanted to catch Roggenrola. (Catching Roggenrola ultimately didn't seem like a "feat"--it was acquired in an easier manner than Iris's Emolga. I think I may have lost track of the Roggenrola at the beginning even, and that Ash may have caught another Roggenrola... I was drowsy when I watched the episode though.)
Oh, Tepig was strange (weak?) in this episode, and Roggenrola seemed weak as well at the episode's end (as to how it seemed in the beginning, blocking Oshawott's Water Gun attack). Ash's commands to Tepig I found baffling--Tepig really needs another kind of move, perhaps Wild Charge, or maybe Head Smash. I'd doubt that it would ever get Grass Knot, unless all of the Unova starters belonging to Ash learned it.
