...Hmm... You look quite indifferent. I thought the person you mentioned was that alchemist, so I brought you to him but... was he the right person? I guess not... I mean, unlike you, he has that dark, gloomy shadow that's cast over him. He's someone that's hard to approach.
#b1) Any idea where he is?

Where? Hmm... there's no such place where he resides. It's just a afterimage from the past.
#b1) Can you tell me where he is right now?

There's no way you can tell. Like I said, it's just a afterimage. It's nothing important, so just forget about it.
