No, it's fact,
if you had called an attack then you would have won.Uh, I mean, the crystal hovers above Iris before she transforms. It's not her. All signs point to the crystal being Colonel's memory chip.
When X encountered Colonel, I wouldn't put past him that he hesitated to kill Colonel, or maybe just wanted to disable him and not kill him. As for Zero, he charged at Colonel in Memorial Hall.
It's extremely hard to disable someone when they are intent on fighting to the bitter end. When they're threatening you're life, sometimes you don't have the luxury of avoiding the same in retaliation. You think either X or Zero wouldn't have spared Dragoon for further questioning if they could have?
Zero lunging at Colonel was before the bulk of Iris's pleas. As I mentioned in my last post, he grows a lot more hesitant as the game goes on. Memorial Hall, to me, reflects Zero's X1-3 attitude of shooting/slashing first and asking questions later. Since then, however, he tends to instead let enemies ramble before taking them down.
I'm gonna say that Zero fought both Colonel and Iris for it builds up a tramatic effect on Zero since he was friends with Colonel and had a thing for Iris.
Well, Zero DID fight Colonel at some point, that's established in X5. But that could be either Memorial Hall or Spaceport, which one is not specified, and Skiver's dialogue works either way (better, I think, with Memorial Hall).
But as for traumatic effect, Colonel was neither the first nor the last friend/ally that Zero had to cut down in the line of duty. Mac, Blast Hornet, Web Spider, Spider/Redips, and Elpizo all come to mind. The impact on Iris is what Zero's concern was, which he outright states before the Spaceport battle. Likewise, Iris is the source of Zero's remorse in X5. He can shrug off discussion of Colonel easily enough.
No, not in that way.
Aw, that's no fun!
So, if I'm understanding this correctly, technically if X faces Colonel, then Zero might not have ever had to kill Iris?
Iris likely would have faced Zero anyway because she wants him to stop fighting against Repliforce, both for the sake of her Reploid-only fantasy and so that Zero doesn't get killed in the process. The problem is that she "goes out of control" upon installing Colonel's chip.
