Mycroft and Watson in “Unfinished Business”

Mycroft

(after being subjected to a staged event intended to suggest that Eurus is attacking him) Doctor Watson, why would he do that to me? That was insane!

Er, yes, well, someone convinced him that you wouldn't tell the truth unless you were actually wetting yourself.

Mycroft

Someone?

Probably me.

Mycroft

So that's it, is it? You're just going?

Well don't worry. There's a place for people like you; the desperate, the terrified, the ones with nowhere else to run.

Mycroft

What place?

221B Baker Street. See you in the morning. If there's a queue, join it.
