'Serena and Blair will be so on the outs over what may or may not have happened with DB that when Prince Louis comes around, Blair accepts his proposal.

Then Chuck fights with Russell Thorpe, Howard Archibald, and his uncle Jack over control of Bass Industries, and discovers Raina has been hooking up with both himself and Nate on the side.

Somehow Chuck & Blair reunite for a passionate last night together to figure out what will make them happy in the future.

Meanwhile, while Chair are having their rendezvous, Russell Thorpe decides to get back at Chuck and the Bass family once and for all, by setting fire to part of the Empire Hotel...accidentally killing his own daughter Raina in the process.

Blair goes off to Monaco with Louis, as Chuck is then accused of the Empire arson and Raina's death, but wanting to spare Blair any grief or a royal scandal he doesn't use being with her as an alibi...and ends up being sent to prison for a crime he didn't commit.'

Я правильно поняла: Чак и Блэр проводят вместе ночь, когда Рассел случайно убивает Рейну. Но Чак, вместо того, чтобы воспользоваться Блэр в качестве алиби, отправляет ее с принцем в Монако, чтобы не приплетать королевскую семью и Блэр к скандалу. Так?
Жестоко, конечно. Но вполне вероятно.
Помучаются, конечно. А потом Блэр не выдержит, плюнет на принца и спасет Чака. Очень в духе Сплетницы :))
