Before Luka's wagon Ratchet is on Shuji and then beating Cryo hard, voting Reloaded, Rej only mentioned once in a general PoE
after Luka's wagon: yep Rej sure scum:
Well that's because it was a particular post from Rej that made me think this:
This one. At this point it because clear he was just making his positions up as he went along, for a number of reasons. First is the way he decided Luka was scum off the back of Luka criticising his post. Rej is more emotional than that. He would take his input being treated that way differently, he wouldn't just say they were scum.
The second is the conviction behind it doesn't match up. He is sure Luka is scum despite Luka only saying his post was bad. It's not a measured response.
So after seeing that I said "yeah he's scum".
