During Game of Thrones S03E03 Tyrion donates his squire Podrick a stay with three whores as a reward for his services, especially during the battle of Blackwater. But when he returns he gives the money back to Tyrion saying that they wouldn't take it, much to the wonder of Tyrion and Bronn:
Bronn: What did you tell them?
Podrick: I didn't tell them anything.
Tyrion: What did you do to them?
Podrick: Lots of things.
Tyrion: And they seemed to like these things?
Podrick: Yes, mylord.
Bronn: Of course they seemed to like it, they're paid to seem to like it.
Tyrion: Only they weren't paid.
Bronn: What you saying, those ladies enjoyed him so much they gave him the time for free?
But I wonder, was there anything more serious behind this scene or is Podrick really just an exceptionally good lover? While this question might seem trivial or speculative, I couldn't help but feel that this whole incident and conversation didn't contribute anything to the overall plot at all (especially in light of the IMHO rather minor role Podrick has in the story anyway). Yet, on the other hand Podrick's loyality doesn't seem in question when judging by the rest of the story so far, so it isn't too likely that he made some sinister deal either. So was this merely a little distraction or cheerful addition to Podrick's character or was there actually more to it that ties this scene in with the bigger picture (or maybe the source material is more elaborate)?
