"Does Rocky hate Stratt" I think it's more complicated than that. On the one hand, Eva Stratt did what she had to do to keep Earth safe, there was hardly any time for her to sit and think and do things more ethically. She did what was necessary and Rocky can respect that. On the second hand, he doesn't think saying a lot of if not outright mean then definitely psychologically damaging things to Grace and putting him in the Eridian torment nexus was really the best way to go about it, she could've been more humane about euthanizing him. Now he has to deal with a traumatized leaky space horse who thinks no one loves him and needs so many medical procedures and can't do any of them without having a panic attack and also if he dies from any of the five million things he could die from, including the aforementioned "not thinking anyone loves him" thing, then Rocky is going to fall into an endless pit of despair so that was. Rude of her. On the third hand, if she hadn't strapped Grace to a rocket and chucked him into space, he would've never met Grace, so really, how much can he complain about it? On the fourth hand, the only reason that even happened was because Stratt is at least 54% liable in a major engineering disaster, so now he has beef with her from a professional standpoint and he can't just let go of that until she faces the Eridian justice system which isn't happening. On the fifth hand, Stratt is human, and that means she's every bit of a leaky space blob that Grace is and really, how mad can you actually stay at a gooey alien care bear thing, long-term, and how much energy is Rocky willing to put into finding out when Grace doesn't seem to be all that mad at her, just really sad about the whole thing?
