Dragon Age Origins Unique Extended dialogue with Guardian with oversized party.

So i've been playing this game with basically ALL party members in the group running around, and pretty much all interactions with dialogue rarely allow for anything more than just the 3 primary companions to interact, occasionally glitching with some others, but mostly inconsequential.
However when you walk up to the Guardian after killing the High Dragon, all characters excluding lohgain are accounted for and for the most part interact (dog/sten and zevran don't actually say a damn thing but they are present and look around).
I found this rather interesting.

No Zevran?

Or sten or lohgain that he doesn't even appear in the cutscene.
I think it's a hard-coded function that beyond a certain party count certain things begin to really break.
For example, with all 11 party members plus 4 having summons, 3 will fail to follow the party and remain only to show up via teleporting to the party.
Honestly though, I spend most of my time loading dragon age due to its constant crash to desktop on newer systems, remember trying to play it years ago and having the same experience. Save relentlessly.

the guardian asks him about the woman he assassinated which was in love with him and if he regrets it he gets angry and before the guardian can finish his sentence he says yes to shut him up
