They literally spent the entire chapter calling the mc reckless for it. Thats why they asked if shes gonna marry ciel now since they slept together . (Plus this is prolly the 2nd time they slept together since this lifetime)
It was so subtle that I wasn't sure if anyone actually knew what had happened... For example Aiden only mentioned how Ciel had hurt Irene, which sounded to me more like worry due to her weakened state as a guide than for having intimacy with his brother.
I mean, her family don't even know yet that she is a guide, because apparently all of them are blind and stupid despite the many times Irene took care of Ciel, Morgan and Aiden and they suddenly POOF, improved miraculously?!
Ur right thwy were rlly vague but i think when Irene passed out, Ciel wouldnt have the time to dress her up. So her being naked with bitemarks prolly wouldve been seen by someone...at least the maid. Rose prolly clocked she was guiding and thats why she asked. Aiden prolly thought Ciel assaulted her and thats why he was worried abt her health than them fucking. This is js how i saw it ♀
Also i agree, why would Irene be training the "only" guide if she wasnt one herself i thought she was out to ppl in Closhe but ig not.
So they did the deed and absolutely nobody is going to even mention it???
And they two are just going to go past it like nothing happened? WHAT THE HECK!!
