Regarding if Mydei intended being suspicious or not a cn theorist community found a intresting finding:

-There two point
-First point
-On their drip marketing the word 'Mydei', 'Mydeimos', 'Evernight' and 'Cyrene' have quotation mark on it
-Evernight established in both in her drip marketing and main story 'Evernight' is just an alias
-If Cyrene is also an alias/false name there implication here
-Second point
-Take attention on Anaxagoras/Anaxa
,Hyacinthia/Hyacine, Cifera/Cipher and Helektra/Hysilens there no quotation mark on it
-Because even Anaxa, Hyacine, Cipher and Hysilens is just nickname or alias for Anaxagoras, Hyacinthia, Cifera and Helektra they still see it as their name
-But for a person called 'Mydei' or 'Mydeimos' they don't see 'Mydei' or 'Mydeimos' as their name at all

Take that as your will.
