I don't feel that way, don't worry.

I would say Goshikuro might be a bit paranoid and want to target her if he can sense her spirit energy. But I can also see him being super arrogant and getting cocky with how he's been able to hurt Yoko thus far, taunting him in a way. So in that case, it could be the lackey who targets her to be safe. So I can see either one of them wanting to tag Botan. But again it could be because she's clearly important to him or that she seems to have some kind of spiritual energy and is seen as a threat sent from say, Spirit World.

I'd say the detection would happen in his human form solely. I don't know if Yoko is [i]too[/i] interested in the matters going on but he could be intrigued by them, if anything. I would say it's possible the lackey could be distracting Kurama while Botan is off trying to kill herself and maybe someone mentions having seen her with a knife or something. Maybe Kurama just adds up the fact she's been quiet/a little snappy/distant/etc and is suddenly gone? Or maybe Yoko tries to seek her out and locates her and mentions to Kurama internally that she's been corrupted? Kurama then rushes off to her aid?
