Explanation/summary by Disqus user: The wisest pickle
Okay!
I had to join just to post this comment because A. This DJ is amazing and B. A lot of people seem confused/unsure of its meaning/plot.
Host Is Down - refers to two things (or multiple things depending on how you look at it). With a Sci-Fi basis no one questions host being the 'Master' but really think about it not from the beginning of the story but the end.
'HOST' is down. In the end we see that by the rescue crew's technology they can't identify the master as being alive. They're able to easilly repair the android but quickly deem his master as dead.
This would imply the technology isn't foreign to them, so neither the ship or the master are alien in nature - HOWEVER we all can see the master ain't exactly normal anymore.
HOST' is down. The master is dead by their standards and likely with the ship in the condition it was in during most of the plot should have been 'rotted', however his body has made a transformation where even with the weak power supply of the ship is able to sustain itself.
The android says his master was injured but the master's body was pristine and even the android seems unsure. "Was it a malfunction?" The android however is in TERRIBLE shape, his body has been butchered and both him and the state of the ship suggest something horrible happened. (The parasite's initial success at claiming a host?)
There was an 'intruder' but the thieves who try to rob the ship during the DJ notice supplies are untouched. By the end of the story we know the intruder was the alien and it doesn't need human supplies for food.
When the android begins to bug it seems like he's speaking gibberish but he's actually telling the truth of what happened that he can't quite comprehend.
My Master (Damaged) My Interior And Deeply Inserted His Hand Snake (Creature)" - the snake creature being the alien we see in the ending.
The android has an imperative to always save his master's life which likely directly conflicted with the fact his master likely hurt him/was hurt by the alien. The host/master was badly injured either in the alien's attack or in the android's defense and if the android had been a person likely would have died with his host but the android preserved the host.
The android however does seem to comprehend that his Master's body now functions in a new way. I don't believe he intentionally meant to sacrifice the rescue crew, he says he wishes he could have introduced the thieves to his master ("Look Master these are the people who saved you!") and is disappointed.
When the rescue crew tell him his master is dead he disagrees and seems certain the master will awaken (which he does). The master and the alien likely have formed a warped symbiotic relationship by now. The master does not Attack the android again but he does speak in the final panel which is left intentionally vague, but the boxes are clearly placed on the master's side.
He regards the humans as changes of clothes, one flesh suit for another and apologizes to the android who does seem to almost hesitate. "...yes." (Why I believe he didn't mean to intentionally sacrifice humans to the host, but in the end the android's imperative/love is clear: His master is his primary concern, he has replenished himself through consuming the humans and now he will clean his mess).
This is long as shit but this DJ was well worth it and I just wanted to offer some in sight for people who also loved it but didn't 'get it'.
