As far as everyone knows, Smg4 and Smg3 are frenemies. Of course, some of their close friends suspect there's more to it than that, but the two meme guardians put up a good front, so there's really no way to determine that the two are anything more than that. But if that's the case, why all the lies? And the secrets? And the inside jokes? And the closed doors? Maybe they're finally bonding...because they would tell their friends if they were in a relationship together... Right?
