Smile of the best girl

Spoiler:

Okay so the monobear tried to prevent them to enter the headmaster room. Well I'm sure he'll open it in the next chapter considering how he works. I mean, he tried to prevent Naegi to look at that photo before but then allow it just like that in this chapter. He's probably doing that if the situation is favorable to him.

As for the photo...I couldn't see how that would be fake considering the situation. In the first place, how could someone fake a photo as natural as that? I think it's completely reasonable for Naegi to think that the photo isn't fake and believes in what Monobear said. Kirigiri saying that kinda seems that her anger towards him clouds her judgment, but... Well, considering how their dead friends are acting like that in the photo...I guess that will surely confused them a lot.
