In volume 42, it is revealed that Dr. Araide is Vermouth in disguise. And it is also mentioned that Vermouth disguised as her mother - actress Sharon - also. But WHY DOESN'T SHE GET OLD ?!! I mean: she lived as Sharon for YEARS, but now she looks like in her twenties!!

Is she disguised as Sharon, is it probable that she had killed the real Sharon?!

Vermouth that time is her mom, this time is herself

Yea, that's why I wonder why she doesn't get old at all.

I always wonder why??maby she eat samething to became like that

My best explanation: Vermouth's mother , Sharon, was Shinichi's mother's friend (Yukiko's friend). Now Yukiko is 38-40, and I think Sharon's age should be approximate to Yukiko's. Yukiko doesn't look old at all, and so I think neither does Sharon... HOWEVER, THIS IS WHAT COUNTERS MY EXPLANATION: Sharon may not look old, but why doesn't Vermouth either?!!!! Vermouth = Sharon's daughter; if Vermouth has lived that long (from her mom's generation to hers now), why isn't she old??!!!

I just read the Vietnamese version of that chapter, and I think that there must be some mistranslations in that part...

ummm....Judy from that time is about...6, now is like....25 approx., so Chris now is also 25 , Chris back then is 6 also. Then the invader is Chris's mom (Sharon) with cap on, Yukiko that time is about 25, Sharon is, too. So Sharon that time confused Judy, thought it was Chris (mom-daughter lookalike happens ). BTW 38 is old, cuz Yukiko always puts on makeups, to make her younger again

I think she took another form of drug.
