Entourage help

Hello!

I would like to ask help understanding the entourage keyword for the giving order part.

So a specific case Tarkin has entourage Vader.

In this case how exactly it plays out? (if it is in range 2)

Both Tarkin and Vader has their order token in the mix, if Tarkin getting his activation he can give a free action to Vader? or 2 action? With this Tarkin lose 1 of is his action from his 2?

So while Tarkin is activated, with the giving order part Vader makes an action?

And after (or before) Vader will still get activated from his order token from the stack normally?

Thank you
