Hannah-shikari said: “I love you.”
I think I replied with: “Aw, thank you, Hannah-chan. It’s always nice to hear that you are loved. I love you, too, in a strictly platonic, sibling-or-friend kind of way!”

Camiechan said: “I’m pregnant with your baby (and Hannah’s apparently…)”
I probably said: “Uh… … .. I demand a DNA test as I don’t recall taking you to bed. That said, I have been drinking an /awful lot/ lately… Shit.”

Themoonlightthief said “I love you.”
My bumbling response was along the lines of: “Ah… … Kaitou-san…” Hard swallow, scarlet face. Then a hesitant smile. “I… I love you, too. So very much.”

Themoonlightthief also said “I’m pregnant with your baby.”
I imagine that this is what I sent in return: “What?!  Again? …or still? With twins? Wait, I’m confused. Is this supposed to be new information or are you reminding me that we’ve yet to pick out curtains for the baby(or babies)’s room?”
