Yeah, we still don't know about the spider droid. But Miles gave the androids a name in a tweet. Oh well. I think Alpha and Omega still work well.
Ahh I see then people added it to the wiki. I chose Alpha and Omega sentinels because I used the knight in the white trailer as sentinel as well. Seeing as they are all Schnee owned (Possibly) then it kind of had a name continuity.
Yeah, the Knight might possibly be Schnee owned. I dunno, there are a lot of theories just floating around about what the Knight is. Sad thing is though, we're probably not going to learn more about it this Volume.
