Does Cassidy exist in the games?

(As a seperate entity from the puppet and BV)

AFAIK only 7 children names have been revealed in the scott era games - 4 from the gravestones, 2? from the logbook and 1 from Henry's speech

If we fit these names onto the animatronics we get the 4 classics, GF, Puppet and Baby, where 5 names are basically confirmed leading to 2 remaining names - Cassidy and ?Dave for Puppet and GF/BV - which implies one of them were a part of the MCI

Assuming Cassidy was seperate and for the 5th MCI kid, we wouldn't have a name for either Puppet or BV. However BV almost certainly is in the logbook as altered text and likely named in the logbook, leaving being puppet.

I find it weird that Scott would want us to use the books to find her name especially since he doesn't not give us her name in FFPS, implying that we had to use other methods to find it(the logbook?)

Not to mention that most of Cassidy's appearances can be explained by BV(most of ingame appearences) and puppet(logbook)

The games get a lot cleaner if we don't have to account for Cassidy being seperate- especially TOYSHNK and Happiest Day/FNAF world and also helps to give the scott era games better closure.

(TBH CassidyAfton also makes a decent amount of sense and would make the logbook more consistent)
