(READY? THIS IS THE LAST WARNING! SET? LET'S GO!)

Alright. So, this episode just flat out amazed me. To be honest, it held traits that an episode (with a drive for this kind of plotline) should have:
-Character thoughts
-Conflict with Power
-Memories
-Confliction
-Overcoming confliction, but not completely
-Action
-Suspense
-and a cliffhanger ending with surpisment
If you couldn't tell, my favorite sans is actually Cross. He has an interesting character and backstory, which was somewhat explained, but still vague. That leaves the audience with making theories or giving Cross a mysterious side to him.
I loved how the creator  took references from her tumblr, such as: The fact he loves chocolate and tacos, the fact that he hints back at when ink introduced him to tacos, the soul from the truce which Error had (I believe that was what Ink had), and the X tale characters from his memories.
It made me feel more in depth with the storyline, which I gladly appreciate. I even found myself feeling what the characters felt, making the experience more enjoyable.
This episode had its ups and downs, making it a well balanced episode.
I greatly appreciate the creator for their hard work and effort put into the product.
However, there is one issue with this: Time.
I am not saying that I am not patient. I would GLADLY wait several months for the next part, because I know how long it takes to draw, shade, edit, and work on each slide. It takes time to animate. Also, The creator of Underverse does other things, such as update other comics, answering questions, and even making her own story!
To think that this all came from a single person is mind blowing! It seemed impossible! However, it wasn't.
Overall, I enjoyed this. I can walk away from this episode with an extremely positive attitude. I am excited for the next production, and cannot wait to learn more about the story.
This is Dark, signing off.
