Fiona became Frank

I don't know if it was obvious for everyone, but I figured that while watching one of the episode of S9. She's a drunk, sitting at the bar, and Frank enters and says "you're sitting at my place". At this moment, you start to see the resemblance. Yes, she is a bad drunk instead of a good drunk, but I still see the similarities the authors might wanted to point out between Fiona and her father at that point in the show, just like they did with Lip when he was an alcoholic. Just wanted to see if I was the only one seeing that stuff!
