I have a question about dice that are forced to resolve out of turn? The card "Doubt #80 SoR" makes your opponent re roll a die and resolve or remove it. Now if I was to force and opponent to re roll a "Force Speed" die that lands on the special, aka 2 turns, would he remove that dice from pool because its not his turn? Or would he take 2 actions right there? Was confused during a recent game. I assumed because its happening during my turn that he would remove that particular die, unlike a shield, damage or disrupt even, or would he bank those 2 actions until his turn began? Hope this is clear what I mean.

Any help is greatly appreciated

If additional actions a gained (in turn or out of turn), the person receiving the actions must immediately use them or lose them.

In your example, doubt would force the opponent to resolve the die to gain two actions. The opponent must immediately use those two actions or decline to use them. After the actions are taken or declined, it is now the opponent's turn and they get An action.

Moral of the story: Force Speed is not a great target for doubt.
