My Thoughts Of Some Lines From a Behind-The Scenes Video
I watched this clip early on (before episodes 25-26 were released), and I imagined that some of the lines were from a deleted episode. While I like what they did better, and it was entirely me just jumping to conclusions, I thought I'd put my thoughts where some lines fit in this imagined "deleted episode".
The lines that caught my attention were them talking about the map to mount Tyranus, as well as "we're not saving the realm until we get some answers", "this is awesome. Our first quest." and "She may be short, but that dwarf can jump." I will be going in order of when I thought the lines would appear in the episode.
The first of this is "we're not saving the realm until we get some answers." I imagined that Nova Terron or some other person the Mysticons didn't trust (as I've mentioned earlier, I had a feeling the Astromancers would be evil, so them not being trusted wasn't that outlandish) were about to send them on a mission. Arkayna, and perhaps the other Mysticons, weren't sure about going on the mission, and wanted answers. This is kinda close to what happened, as Arkayna was demanding answers for something.
The second line is "This is awesome. Our first quest." I thought that Zarya was just excited about going on a mission. And while it did seem odd that Zarya was excited, given how she felt about working with Arkayna and Em, she did seem happy about the powers, so maybe that played a role. And before anyone mentions it being related to her and Arkayna being twins, it's possible that I've watched this before Arkayna having a twin was revealed (I forget exactly when), and even if I did think they were twins, I did not expect Zarya to be so happy about being twins that she'd mention this being the first quest as sisters.
The third one is the part where they talk about the map to Mount Tyranus. I thought that part of their mission was figuring out where to go, and they found a map that would lead them to where they had to go. While this could have been before the "until we get answers part", they seemed enthusiastic, while at least Arkayna had doubts. However, this was the closest, as they did get a map to Mount Tyranus. Granted, it was an easy line to guess. One thing I noticed was that they changed who mentioned it was Mount Tyranus, as Evany Rosen (Em's voice actor) recorded that line in the behind the scenes, but Malvaron said it in the show.
The fourth line, and the one I was farthest from, was "she may be short, but that dwarf can jump". I thought that, during their quest, Em does a jump that impresses Zarya, making her say that. Granted, I didn't expect Em and Piper to use Choko as a basketball (or I suppose, portal bag ball), or for Choko to like it.
Overall, I think the lines fit great where they were in the show. However, it would be cool for them to have had a true "getting to know you" quest, like the one I thought the lines came from.
