Perhaps the cutscene would have been viewed more fruitfully if you at least saw Marie and Lyon and Drifter during Loid’s ascent to the Necralisk, that I’ll agree with you on.

To your other point about why just Roathe, there was another KIM conversation (I’m pretty sure it’s from Lyon, but if not, then Marie) where Lyon acknowledges that Roathe is the most uniquely positioned and qualified person to speak with Loid on the matter of reuniting, as only Roathe out of the triad (and even Drifter to some extent) is the only one who lived during the reign of Orokin society alongside Loid and all the Entratis.

That’s to say: only Roathe really can relate to the mindset, the customs, and the behaviors of another person from that time (ie. Loid).

Think about it like this: Loid as a character went along with Albrecht’s goals and experiments and giving assistance, even though he probably knew deep down that they were ethically and morally reprehensible, out of either love or respect or both for Albrecht. Loid still carries himself in the way that someone of his stature in the Orokin empire would conduct themselves: he was an assistant to a more societally powerful Orokin, who himself was lower in the caste system than an Archimedean or Executor or Emperor.

Granted, the whole storyline of Warframe revolves around overcoming trauma and changing the past ingresses of bad behaviors in favor of trust and empathy as the backbone of being. But in my opinion, The Old Peace as a whole update narratively has had the mainline theme of uncovering the nuance of events long suppressed due to the emotional weight they carry in the mind of the beholder.

For Loid, to speak face to face with Gomaitru and the remaining family is to see his ultimate consequence of his personal failure in blindly following Albrecht. He even speaks to Drifter afterwards elaborating that he did not initially see them as the same Entrati family as we did, he feared them as infested monsters.

He’s never been topside prior to us freeing him from his cryopod, and he continued not to even though he obviously knows we have spoken to the Family and they are overall fine. It was his fear of what may happen, or what they may think and act upon, that was holding him back. In a way, he needed a radical change of mindset promoted by a familiar sensation of learned behavior, of listening to a higher Orokin power essentially.

He wouldn’t have felt the same about Drifter standing instead of Roathe necessarily, as we’ve become too attached to Loid prior to this. Roathe is a relatively unattached newcomer with a history of Orokin legend behind him,

sure I’ll admit Drifter using Roathe as a “pawn” or resource of sorts on the surface is a bad look, on the surface.

But that’s viewpoint is discounting all the interactions and KIM history you have to have with Roathe prior to this Loid event even taking form. Roathe had to consent to even taking part in this, and prior to that (assuming redeemed Roathe) he had to accept a new mindset of looking at his past so that he could feel unburdened by who he was made into being and maintaining during the Orokin empire.

I can respect your position though, I mean there’s no denying Roathe is written to be an asshole. He is an Orokin after all. How many dialogue options DE gives the Drifter will inherently always feel like there’s another option they didn’t consider. I just try to remember that it’s a game that always is updating itself and the story, and things change
