Bad batch, spoilers
I think having Wrecker die in place of Tech could’ve had a much more emotional impact.
Wrecker is someone who doesn’t get very much physical development, nothing about what he tries to be changes. (Get me clear him being strong is his thing he can keep that)
but if we swap Tech for Wrecker during his death you can have this moment between the two; where Wrecker tries to use the code 99 what he’s trying to do and Tech shoots him down, that he doesn’t know what he’s talking about. Then through his insistence Tech realizes he does know, and he knows ALL the codes, he made an effort to learn so he could protect Omega better.
