[Main Spoilers] Varys was a little different.

I've never seen Varys run before and you could see Dany's concern when he came rushing forth. Not much can unsettle that man except for Red Priestesses and apparently entire armies and fleets getting torn asunder. He also was a bit more expressive when talking to Melisandre. I've been studying his character throughout all 7 seasons because I sincerely believe he is a hero in this overarching story.
