Ah, shifting it around to her. Clearly he doesn't want to talk about his Ren, which is fair.

"...It's a long story. Involved another crisis back home. Reality was being altered, and..."

She trails off. Honestly, it's a lot to throw on someone, especially a version of Akechi... so she really shouldn't say much.

Instead, she shifts gears.

"I've been looking for him. I believe he's still out there."

...Or at least she's trying to. From the looks of it, she's still suffering from grief like her Akechi died though.
