I don't understand your question. Are you asking "What if it's 'only' an EA?" Or "What if neither an EA or a PA turns up?"

If it's the former, I'd strongly urge you NOT TO MINIMIZE IT. Only DAMs say "only" an EA (just ask a woman what is more damaging to her heart).

If it's the latter, then you at least will have your answer, and that will change your strategy and tactics.

How can it possibly be bad to know?
