Quick question, just wanted to make sure I was playing this correctly.

Turn 1.
I have Alfred and the Piloted Batmobile. Alfred take a power action to make a support roll on the Batmobile. Alfred receives an action token.

Alfred takes a free action to become the pilot of the Batmobile.

Turn 2.
Batmobile, with Alfred as it's pilot takes a power action to Charge. Resolves this action and an action token is placed on the Batmobile. Batmobile is given a free action to eject Alfred.

Turn 3.
Batmobile Clears.

Question: When does Alfred clear the token he took for using Support in Turn 1?

He would retain the token that he had gotten during Turn 1, and would clear that token per normal at the end Turn 2.

And the token would clear if he was still in the Batmobile?

Correct, because he was not given a Non-Free Action.

this is pretty much how i played it the other night. nothing in the rules state that he loses the token when he becomes a pilot, so it would stay.

Note that if Alfred were to get another action token on turn 2 (say...using a TTPC), then he wouldn't clear.

I have a question, two really, on this Harpua:

How do you give a Vehicle "PILOT" a Theme Team Probablity Control action token when they are "Off the board" piloting the vehicle?

From what square do you draw the line of fire?

You don't, but he could use it after ejecting.

Thank you for clarifying. It sound like you where saying that he could on turn two while he was piloting the vehicle.

In turn 2.
After a Charge, Alfred can eject the Batmobile, and other friendly character can climb the batmobile as pilot?

Yes, both are Free actions and as long as the other character was not already a Pilot that turn.
