They have done worse, like Ash owning Tranquill and in the preview of the first Don Battle Episode, it showed a Tranquill battling, but it belonged to a CoTD. They could easily have a Gothita here and then a Gothorita like 2-5 episodes later with 0% connection.
That's completely different. That was just a matter of who it belonged to. Here we have a pokemon, whose already debuted with a fairly major role, getting another episode dedicated to it, and its evolved form appearing in another upcoming episode.
But I find Gothita more of a girls' Pokemon.
Arbitrary, and Chikorita/Bayleef is also feminine in design, and Ash got one.

That's how I basically think it's going to go (minus Jellicent), but with how her team's been going, I wouldn't be surprised if she had more masculine pokemon.
