This is hard because literally almost everyone knows about it. But, if you mean an official Sibuna I think Joy. As much as I don't like her in Season 2, she knows so much information. I reckon she'd be a humongous help to Sibuna.

Another person with brains would Mara. She is basically a girl version of Fabian but she isn't the type of person who would be adventurous like Nina. Even though she'd stay and translate all the hieroglyphics with Fabian, I think she would try to go on an adventure, and then do something wrong.

This is really a stupid question, because everyone is 'in it' except Mick.

So basically my options are
•Jerome
•Joy
•Mara
•Willow
•Mick

So I don't know.

Probably Joy or Jerome.

I think they're both super sleuthy and they'd both work well in Sibuna, so one of them.

So ya.

Jeroy!

Who do you wish was in Sibuna?
