I really liked the newest episode. I also feel like it's worth mentioning that the episode was called fucking Dragon Quest. I really like Dragon Quest, so I thought that was cool. But regardless of the title, the episode was still really enjoyable to me. The story and message were both nice along with the humour. As for Twilight not being able to teleport them at first, I just figured that it was hard to teleport so many ponies (and Spike) to such a far away location so she failed the first time. But now that you guys mention it, it seems rather plausible that it's foreshadowing to something larger.
Also, regarding backgrounds, recently my wallpaper has been the angry faic wallpaper from the downloads page here on NG. But after seeing that neon pony wallpaper Snuff linked I just had to change it. Thanks for linking it man, I'm loving it.
