老师好。我在阅读一篇文章时，有几处困惑的地方。 

One of the actors up for an Emmy - Gwendoline Christie who played Ser Brienne of Tarth - had to nominate herself for the award despite having one of Benioff's favourite moments in season eight. 

 这句话开头的up for 应该理解成是什么意思呢？ 

 In all seriousness though, it was a mistake that Benioff admitted embarrassed the pair. 

 逗号后面的是强调句型吗，是否可以写成Ben...admitted a mistake that embarrassed the pair 吗？ 谢谢老师。
