In Westworld there are a number of - almost certainly - deliberate discrepancies with Emily's character, for example:

* She goes to considerable lengths to ensure that a sex partner is really human, yet later states to William that she went to the pleasure palace in Raj-world and "rode for a couple of days there"
* She states that she never saw the music box again, yet she has the memory card that Juliet placed inside it
* When William asks how she found him, she just said she "searched everywhere". But a more obvious explanation was she learnt tracking at the same time she learnt Lakota...
* Her body is stacked with the others (tho' admittedly it is not clear in which pile)
* She appears in the post-credits scene of the finale

So was/is she a host or not? Or could there be one of each?
