Are you pretending to be [my] [dead] [best friend] Sherlock?

[No.] I am. [That is a leading question, John.]

Am I to believe that [you] he is alive? Or is he texting to me from [heaven] beyond the grave?

Whatever you like.

Why are you doing this?

I had to.

Sherlock?

[Yes.] What do you think?

I don't believe you.

Good.

But… I want to believe you.

Why?
