The professor being clueless at the end and telling them to delete the data feels somewhat forced in that moment, but it's still a great read. Especially love the implications of what happened, and that it makes you think about how this will play out in the long run, will they realize during a med scan that there was poison, how is K-7S2 hiding this from the Delta Lab that is supposedly monitoring all of it or did they miss it, etc etc. It sets up a whole lot of possibilities, which is a big achievement for a 1k word story.
