I'm so sorry I cannot provide a source right now because it is late at night where I live and I should be sleeping, but I think recall Vriska saying that on the new Earth she would throw Gamzee into the ocean at some point? And I think maybe she said something about how it would create life in the sea although this all may be incorrect and from vivid dreams please don't hate me I just thought I should bring it up incase it is true. I'm sorry of this bugs you or you already know this ect.

Here.
