I loved it. To be honest, it was a B episode until the end, but those last 30 seconds shot it straight up to an "A," because the feels were just there. Maud herself is an interesting character. She really is
like the other girls in terms of her personal ethics. She's honest, kind, generous, etc., but she's more introverted it seems. I also like Maud's design, her personality, it all works for me, and the thing is, you can clearly see how much she does love Pinkie Pie, and that makes this episode awesome.
