You mean The Mountain
I feel like they've done a shytty job in the show building up the legend of the Mountain. We've barely seen him except in season 1 when he attacked Loras. I feel like throughout the book, at least, there was always someone telling a story about something fukked up he did. Like the time where that innkeeper said his daughter wasn't a whore, and he threw some coin at her and said, "She is now."
I mean...I guess there's still some time. But they need to work on building him up ASAP. He's a pretty faceless character at this point.[DOUBLEPOST=1397603574][/DOUBLEPOST]
Oberyn's sister was Elia Martell. She was a Princess and married to Rhaegar. Rhaegar was a Prince, son of the mad king, and he was the one who Robert so famously slew on the Trident with his hammer. The Mountain killed her baby and raped her with the baby's brains/blood still on his hands before killing her.
He is not a good person
