On the one hand Petyr’s “I loved you, more than anyone” is a gut punch thanks to AG’s acting, but on the other hand:

That fight was over almost as soon as it began. Brandon was a man grown, and he drove Littlefinger all the way across the bailey and down the water stair, raining steel on him with every step, until the boy was staggering and bleeding from a dozen wounds. “Yield!” he called, more than once, but Petyr would only shake his head and fight on, grimly. When the river was lapping at their ankles, Brandon finally ended it, with a brutal backhand cut that bit through Petyr’s rings and leather into the soft flesh below the ribs, so deep that Catelyn was certain that the wound was mortal. He looked at her as he fell and murmured “Cat” as the bright blood came flowing out between his mailed fingers.

He didn’t weep or beg then, he won’t weep or beg the next time he’s facing death either.*
