Agree 100%. I also have a theory about Oryx's death: We all know that Oryx has 2 other Sisters Xi Ro and Savathun. It is my opinion that Eris may actually be working for one of the sisters. If I was to choose I'd say she was working for Savathun- (more info here, must read: https://www.bungie.net/en/Forum/Post/159075250/0/0) it is known that All 3 siblings enjoyed killing each other repeatedly and were filled with envy, while you ponder this, ask yourself this: where did Eris learn how to make this gun? Even Toland who studied the hive could only make The bad juju which did not require us to bring any parts. Is it a coincidence that we have wiped out an entire family tree - Oryx, his Son and his daughters? TL;DR Eris cannot be trusted.
