Which is funny because that is closer to why Gene wanted Tasha to die in the first place-people die in space. It's dangerous. In another episode Gene is noted as saying "This doesn't work. In the future people don't mourn. Death is accepted as a part of life."Airam I don't think has been mentioned again in Discovery.
As for Hammer we will see what they do but SNW will likely follow the pattern of Discovery not TNG.
See,I don't care if Ariam's, Hemmer's, Data's or whomever death isn't mentioned again. Do I feel it in that moment? And the answer is yes for many. Same thing with Tomlinson, Sonak, Terrell, David, Carey, among several others. This isn't a copetition of whose death is better but how an audience member feels in the moment. The fact that in order to feel bad about SNW we sit here and hyperanalyze it makes zero sense. This has created a competition about death! WTF?
