CJ knew to stay silent as she and Amy chased Abbey towards the briefing room. She knew to stay silent as tears ran down Abbey's face, as Amy told her what she'd done wrong, something Abbey already knew. She knew the best thing to do was to take Abbey somewhere private, away from Amy, away from the staring faces of worried staff, away from everything. So she took her to her office, and stayed silent as Abbey silently broke down beside her, Abbey's hand gently in her own. She stayed with her during the doctor's visit, and wished to all God she could be the one leading Abbey back to the Residence as she watched Amy take her home to stay with her until the sedatives kicked in and she could be taken briefly away from her pain.
But CJ had a different place in this administration, so instead she was forced to watch, pained, as Abbey's husband renounced his power to his opponent, who couldn't help but stamp upon the President's pride in the process. So she looked on, powerless to act, as Jed Bartlet signed away his Presidency and went to join his wife to pray, to cry, to await news and the arrival of their other daughters.
She and the others were left behind to try and cope with following orders from a leader they did not trust to make the right decisions. She could see the rest of them felt the same, even those who didn't feel the President should be leading the country at present. They followed Leo like sheep, knowing he would make the right decisions and hoping he could convince their new leader.
But their minds were elsewhere. Their thoughts were with a young girl who they considered a daughter or a younger sister, wondering and hoping that she could be found safe and returned to them unharmed. Their thoughts were with her parents in the Residence, where the President tortured himself by watching the news playing clips of his lost daughter's childhood, Charlie beside him, while Abbey lay momentarily unconscious, her pain taken away briefly by a sedative.
And none of them ever lost hope.
