That's an invalid argument.

So, the risk of Oreki finding out the truth was given and high - otherwise he wouldn't have had what it takes anyway. You'd think betrayed Oreki would be more likely to have a loose tongue.

It's true Irisu would have needed to choose her words carefully in order to avoid giving Oreki the ultimate hint that the corpse never was in Hongou's script. But even if she had lied a little to make sure he starts from the corpse and not before it, she could have told him the truth immediately afterwards, instead of letting him discover it the most hurting way possible.

Considering it was nothing but a club film, the price paid feels a bit too high, both for Oreki and Irisu herself.
