[@Sassy1085] Can I ask you to change your post? 

You never asked to work something out between characters, and you're character wouldn't be able to figure out who mine was simply by hearing their voice.

Identities are completely obfuscated, which I would assume includes ones voice. Thats why they didn't figure out 11th till the end, because he has such a recognisable voice.

Also, I'd like to say that they wouldn't be friends. Or even acquaintances. He hates social interaction with anyone but his close friends, and is scared of people to a degree.
