Should I add an and, change to commas, or leave as is?

[Stephanie Runyon]

Sophia suffered from a dissociative disorder. She displayed four unique personas: Delilah, the sex addict; Neville, the teen who detested males; Evie, the scared child.

I have debated with myself on this. Should there be an and before Evie? Did I use the semicolons correctly? Would there be a better way to write this?

This site supports using the conjunction.

Series—If one or more elements in a series contain a comma, use semicolons to separate them. Include a semicolon before the final conjunction. (Members of the Western Jazz Quartet are Tom Knific, bassist; Trent Kynaston, saxophonist; Steve Zegree, pianist; and Tim Froncek, drummer.)

So adding and would make this grammatically correct, but otherwise, I did write it correctly?

In my opinion, yes.
