Unless I missed some detail, it would've been nice to see why Iris became so attached to Mizuki in the first place.

She has no family, no relatives, and no memories of her past. Under such circumstances it makes sense she would stick to whoever was friendly to her during the hardest years. I bet both the Seras were exceedingly friendly since they are disgustingly good people. I'm not sure it's necessary to know how they met, unless there's some relevance there concerning the current situation. They could have just met by chance, being of the same age.
Considering the new revelations, and with her new emotions being tested, I think it's valuable to understand how deep of an attachment she had to Mizuki in the first place. Their relationship has been so far one of servitude in many ways rather than plain being good friends, and I think that's an important distinction to make. Could be a trope, but if the relationship might get tested now in any way, I figure it would be nice to know how deep their roots actually are with them potentially being a bit more substantive than a character simply being friendly.
Not that it is really all that important, but I think it could add something to the dilemma. Not that I think there was more than that, but considering that strong attachment and loyalty she had shown in the past, I think it opens up the possibility for there being something a bit more going on... like say she being ridiculed for her personality and Mizuki stepping in, etc. as lacking in originality as that might be.
