spy on your friend

You follow behind the prince of the realm. You needed to hear what your friend is planning for. Rhaegar walk with the sword of the morning. Arthur Dayne held his hand over the hilt of Dawn, his ancestral family sword. He began to talk to the prince as you try to catch a few words.

"My king. We should be closeby when you battle the usurper on the field. You should strike now while Robert is struggling against our royal supporters up north. If they get to the trident. The war can go either way."

Rhaegar smile to his best friend. "Don't worry my dear friend. We have enough time. But I need you to promise me. You will protect..."

They turn the corner as their talking went quiet. You quickly have to decide between. Trying to keep spying and possibly get caught or give up and go over the new information.
