The editor asks me to wait couple of days
In general the editor makes choices as to how to best get a manuscript evaluated. If one reviewer did not return a review, it is only natural to ask for a new reviewer's opinion. The fact that the editor-in-Chief confers with another editor could mean that they confer whether or not the existing single review is sufficient.

As for time, I am not sure why you question a few days for a decision. Most editors do their work outside of normal departmental duties so finding time for discussing a particular manuscript can take some time and surely five days is not anything remarkable?

So from my view point, as Editor-in-Chief (of another journal), you seem to be very impatient and lacking insight in the everyday editorial business of a journal. I do not see anything strange about what has happened and I particularly do not see any reason for the editor to let you in to the internal work of the journal editorship.
