Can you choose to defend a hero who is attacked on another player's turn, and does Spider-Man's interrupt trigger when an ally defends another player's hero?

Question

Accepted Answer

Heroes can defend any attack if they are not exhausted, even out of the normal villain activation. Spider-Man's interrupt triggers only when the villain initiates an attack against him, so defending another player's hero with an ally does not trigger it.
