Aside from the sadness/disappointment/self-deprecation induced tears, from canon we know that Bakugou is an angry crier, Kirishima a sympathetic crier and Kaminari a stress crier, which, when you really think about it, means that once one of them starts crying the possibility of all three of them ending up in tears is pretty high
The whole episode of “The Depths” is about brainwashing and what brainwashes what.
And eventually the conclusion is this:
Queen Luxia:“Please! The last thing I remember is that organism in the garden falling from space. I went to inspect it. I thought it was a plant.”
(and we are shown this picture of that snake creature)
Hunk:“Wait a second. We’ve been eating that plant. And it’s delicious! It’s so safe and warm.”
Lance:“A-ha! Mind-swishing! It was the plant the whole time. And the queen was the first one to be mind-controlled.”
Queen Luxia: “The Baku has been harvesting us all. We are its food source.“
And we are made to believe the organism was this thing:
The snake is not the organism that fell from space and was mind controlling everyone.
It was the same thing that got Zarkon
This little thing that they let enter their universe through the rift:
The mermaids have been eating food contaminated with that purple quintessence stuff Zarkon has been gulping down.
“The Depths” are kinda telling us what happened to Zarkon before we see it in season 3.
Honerva (or Zarkon) was the first one to be mind controlled by the creature, and the creature is harvesting all life forms in the universe I guess because it’s it’s food source.
(It’s something that becomes very clear after S3E7, but it was right in front of our eyes since S2E2)
Since it doesn’t seem like team Voltron are on to it yet, they just know that Zarkon somehow came back to life after he died in the rift and blame him for all the bad the Galra Empire has done.
Maybe Lance and Hunk would be the first ones to connect the dots and realize the real enemy is that purple demon thing.
And in “The Depth” they got rid of the brainwashing by using a fish..
So maybe someone should throw this thing in Zarkon’s face to save the universe haha
OK no, although that would be awesome.
That was a temporary solution, but it did seem to cancel the brainwashing effect of eating the purple quintessence, so maybe
Plaxum, Blumfump and Swirn could help team Voltron understand what exactly was in that fish that did that in the future..
I mean if they will still be around.. because
The thing is still there when they leave the Ocean planet. They didn’t get rid of the real problem. They just got rid of the snake that was probably controlled by it.
Also if letting the purple quintessence into your system has the ability to brain wash you and puts you under the “Demon Thing” (NOT ZARKON’s) control…
Shiro has been like bathing in that stuff since the start, he got hit with it so many times haha
