OKAY we've already discussed a few things (Castor frandships with Grace and Hector??, Zwei/Grace background?, Reggie adoring Noa and trying to get Castor to loosen up?) but I also didn't realize that Grace and Zwei were in the same graduating class. They should've been on the same ship from Venus when they came to the RAC too, like when you're on the train watching someone who gets off at your stop and you're self-conscious that you look like you're stalking them because they seem to be going to the same place as you and them BAM THEY'RE CLASSMATES..... and Grace is just going to fuss over Castor apparently.
Now I want to know NPC things :> Mine have all been around forever, sorry.
