I will like to start with AbhIya, if you don't mind. After a long time, I actually had a 'Go, girl!' feeling for Pia. I like the way she taunted Abhay about mistaking her for someone else or about wanting to insult her yet again. Yes, I felt bad for Abhay, no doubt about that but I wanted such a reaction from Pia! And it was pretty soft, if you ask me. After her momentary display of displeasure, only on the surface level, she went back to being confused and inquisitive about what all that was about, why they were in the middle of nowhere? Abhay is, well, not sure, I feel, about how to handle this whole situation. I think that is the reason why his actions are not really well-thought of. He just has a goal: to protect Pia from Sid and all this is happening so quickly that he's not getting the time to think about how to go about it in the long run. He's just thinking of the moment, that at this moment, he needs to keep Pia away from Sid. I think a very strong factor which he is not considering is Panchi. Panchi is so closely linked to both Sid and Pia, that despite all of Abhay's efforts, they will meet if not due to anything else then Panchi, herself. She is Sid-Pia's second closest link after Abhay.
Coming to Abhay-Sid. Well, I found it funny I mean, when you're in for a serious confrontation, you don't 'Boo' and say 'Jhoot Bole' without 'Kauwa Kaate' Gosh! I couldn't stop giggling Sid was so hilarious and Abhay's expressions were even more priceless. Like Dolly said in her post, one actually felt like sticking a baby bottle in Sid's baby brother's mouth
Anyhow, on a serious note, what is Abhay thinking? Sadly, I feel he does not know his brother as well as his brother knows him and that can cost him dearly!
One more thing, vampires are definitely not totally free of emotions, I have seen that! They have their own weaknesses which revive their dormant feelings. For Abhay, it was Maithili, then Pia. For Haseena, it's her sons. Just like you, I also feel that Sid isn't as emotionless as he thinks and at this particular point, what's setting him off is not being able to reach Pia. I'm just waiting for something which sets off Chand's emotions now @Precap: I think half the forum will be banging their heads on the walls I, personally, have no issues with another party sequence...
