Chuck & Blair have been through pretty much everything and it isn't abou to get better.
Season 2 Episode 19- "The Grandfather"
As many have seen the 11 সেকেন্ড long video of Blair & Chuck were Blair says "Take Me Now" it doesn't end well after Blair finally realises that Yale isn't going to happen she goes bad. During what I believe to be a party but it might not be Blair & Chuck চুম্বন but Chuck asks Blair for her old self back and she refuses after this Nate checks up on her and Blair holds his hand and asks him not to leave. This I think is how the Nate & Blair situation begins. Eventually Chuck tries to get back with Blair so goes to her house but Dorota does not let him past because she knows that Blair is occupied with Nate and then Chuck will try to get Blair back enrolling on Nate and Blair moving in together finishing the Season.
Season 2 Episode 20-"Remains of the J" Pictures of Chuck স্নেহ চুম্বন Vanessa have been released and many Chuck & Blair অনুরাগী have been shocked. Many know that this relationsip is for Nate & Vanessa to be back together and also Chuck & Blair. Both Chuck & Vanessa want Blair & Nate back so they decide to make them jealous. (This is all I know for this episode).
For আরো information these are the websites that আপনি want to go on:
There has also been pictures of Chuck & Blair স্নেহ চুম্বন but there has also been pictures of Nate & Blair kissing. What confuses me is that it is on the same দিন আপনি know this because Blair is wearing the same clothes and I think it is in the exact same place. Either this is a dream to make আপনি wonder which one Blair finally decides to be with অথবা Blair is playing both men at the same time which seems a bit risky.
All the above is from the পূর্ববর্তি websites that have been provided. I am sorry if it is not 100% true but I am pretty sure it is.
