Mimiroru likes Pikachu? That's cute. From what I can remember, there have been no crushes between the Pokemon on the group.
Aside from that, this episode looks cute. It looks like it's going to be one of those "Catch Snorunt" kind of episodes, with the trainer pursuing the Pokemon for pretty much the entire episode, yet it is playful and fun so it doesn't get boring. I have high hopes for this episode, so let's pray it doesn't disappoint. Though Mimiroru knowing Ice Beam is quite...well, May's Squirtle of it. Though I actually love Mimiroru, so no matter. As long as it doesn't start making Fortresses of Solitude as appeals with it or anything.
I'm happy about Mimiroru liking Pikachu, so I hope it isn't a one shot deal like Meowth loving Skitty. There could have been a lot of comedy that came out of that scenario, but noooooo.
