In season 2, Cersei Lannister captures Ros. Cersei mistakenly thinks that her brother Tyrion is secretly in love with Ros, because Ros wears a Lannister pendant. This mistake probably saved his real love, Shae, from Cersei.
I read that Tyrion gave this pendant to Ros when they were still in Winterfell. Is this true? Was this shown in the TV show? I can’t remember it.
If it’s true, why did Tyrion make this present? Could it be him foreseeing such a situation?
