Culhwch, good observation on Meryn's apparent lack of wounds. Martin does a good job of providing small details without grand explanations. I do not remember any words saying that Meryn was hurt... such as the following.
Cersei fumed as she waited. She heard Ser Meryn's tired voice as the door opened, "The Grand Maester to see you, your Highness." Pycelle's beard and his robes seemed to glide as though carried on a breeze. As the Kingsguard limped out, Cersei chose her words carefully, "Grand Maester, I recall...
Good to see those sarcasm lessons finally paying off there, Boaz....
Fair enough. I still find it unlikely. Let's see if I cant refine my hypothesis. The way I see it, the fight could have ended two ways:
a) Meryn wins, Syrio dies.
b) Syrio wins, Meryn dies.
I'm almost certain Syrio told Arya he wouldn't run, so that option is out of the equation.
I can easily see Meryn winning and Syrio dying, but not before giving Meryn a rap across the knee and a pronounced limp the next day.
I cannot easily see Meryn winning and leaving Syrio alive after being slighted as he was.
I cannot see Syrio winning and leaving Meryn alive. If you can outline a scenario in which a man with half a stick incapacitates a man in plate armed with three feet of sharpened steel, I'll convert. Syrio may have disarmed Meryn, taking his sword. If so, Meryn dies. He doesn't just cop a kick in the shin.
Besides, Meryn is a Kingsguard, who presumably starts most morings with an energetic hit out in the yard. Accidents happen. Maybe he just kicked his toe getting out of bed. Maybe Cersei kicked him when she discovered the botch job he did on capturing Arya. Maybe he has arthritis. True, these are all very unlikely. I'm still standing behind my call that a reappearance of Syrio would be a little too
Days of Our Lives for me...
