Does Mario already know them

[brian3]

It looks that way

[Harry!]

He knows everythinng, rememeber.

[Callum]

Well he's probably met one or two at the auditions.

[GiRTh]

It looks like it. This may be good for Mario. It might stop him from acting like an arsehole toward Ben.

[Frank E]

They all had opportunity to meet each other at the auditions.
Except the new man Andrew, who had exams.
