First of all, if you can recall what your mr. mime was doing shortly before this behavior started, be sure to write that down at some point. Also, film your mr. mime in the coming, oh, week or two, just to be on the safe side. I have a few theories involving mr. mime, and I for one would be thrilled to see if one of them was accurate.

Edit: Fine, fine. We’ll just go right ahead and miss a golden opportunity to discover a mr. mime evolution for the sake of professionalism and “answering the question properly.”
It’s likely that your mr. mime has seen evolution occur outside of your team at one point or another, be it on television, by watching another trainer’s pokémon evolve, or simply seeing it in the wild. He may even remember how it felt if he began life as a mime jr. Evolution is a very common process in the pokémon world, so I wouldn’t necessarily rule out the possibility that he’s simply miming it if the rest of your team isn’t.
The question, then, is why would he want to do such a thing?
If he’s miming another pokémon’s evolutionary signs, then it could be an indication that he doesn’t feel as if you’re giving him enough affection. Evolution is seen as an important time of a pokémon’s life, both to the pokémon themselves and their trainers, and pokémon realize this. They know that evolution pleases their human partners (usually). Thus, some pokémon who have yet to evolve or who have evolved to their fullest but still aren’t quite as strong as others may undergo what researchers call “preevolution anxiety.” It’s a condition in which a pokémon constantly believes that their human partners won’t love them unless they do evolve, so they go through any lengths they can to achieve that process, even if they’re actually fully evolved. If this is the case, it’s important to be there for your mr. mime and to reassure him that he’s important to you. Oddly enough, I do not recommend telling him that you would love him regardless of his form (as this can be seen as invalidating his worry) but rather that he’s powerful enough in his current form. Verbal reminders and affection are fine, but it’s also a good idea to increase the amount of time you spend battling with him so that he can see his strength for himself. Battling will also reinforce the bond between the two of you, which in turn will help dispel any notion he has that you don’t appreciate him as he is.
If he’s miming his own evolution, then what’s actually happening is a reversal of what you would think it is. To put it simply, mr. mime is mentally regressing to his mime jr. stage and forcing himself to relive evolution. There are many reasons why a pokémon may “regress” to earlier stages, but the most common is security. There are elements of the above in this logic; as in, he may be reliving his evolution in part to seek your approval. However, on top of that, earlier stages of certain evolutionary lines are sometimes seen as younger versions of oneself. In other words, he’s seeking the security he felt when he was younger, and to do that, he’s acting as if he’s a mime jr., right at the cusp of one of the most major processes he has ever undertaken. It is, thus, a two-in-one feeling: he gets both the sense of impending approval from the evolution and the youthful, carefree state of his prior evolutionary stage. If this is what your mr. mime is doing, then while you should still reassure him as you would in the previous paragraph, you should also work towards building his sense of self-confidence, safety, and mindfulness. Integrate him into more of your life and set aside time to meditate with him. Both of these actions may help to reduce his worry that he’s in any sort of danger (of being abandoned, in general, or so forth) by increasing your presence in his life and reassuring him that he’s not alone. Any other activity you can do together that will instill in him the idea that you’re there to help will further reinforce his sense of security.
Alternatively, it could be something else entirely. If he’s tensing up or if he looks like he’s struggling to hold something back (say, evolution), it could be a dietary problem. Add more leafy greens to his diet and increase his liquid intake. If he seems to have more energy or that he’s constantly irritable, consider increasing the amount of time he spends meditating, decreasing his sugar intake, and ensuring that he’s getting the proper amount of sleep.
But, ah, if he does evolve, please send the video and any data you’ve collected to [EMAIL ADDRESS REDACTED]. That kind of discovery could stir things up in the Pokémon Symposium, and I would certainly love to see the look on some of my colleagues’ faces when they’re presented with information that proves them wrong about mr. mime evolution.
