I don't like explosions of BLARGLARGELARGLENO so, yeah, let's not ever let our BLARGLARGELARGLENO's explode ever again okay? There's many ways in which Bubbline could become (sorta) canon. I think it's already semi-canon because it's implied a lot in the comics but it's only semi because we know something is happening\has happened between them, but not what. So there's definetely a lot of tension. And even Ice King has his suspicions.

But, in the end, we really don't know. And there are ways in which it can become canon, without them ending up dating. By implying it and not shooting the ship down in the show. And maybe reveal that Marcy has a crush on PB, and that it may be mutual. They don't even have to go any further then that, and it would already be enough. :)
