"Is he really going to succeed?" Luthera held onto Klaus' hand, nervous from the fact that Grey had fought off everyone, with the exception of Tyris.
After Klaus lost, and they all heard Gregory's request, she gave up all hope. The fact that Klaus didn't allow Grey to join him when Gregory asked him annoyed her a little. She felt if Grey was with him during that battle, they would've won the first round.
If they won the first round, then they would've been able to put the pressure on those from the Robertson Family. However, Klaus let his pride get the better of him and he didn't allow Grey to fight, opting to fight alone.
After he lost, he placed so much pressure on Grey's shoulder, and now Grey has to fight off against so many people alone. When Klaus told her that Grey would be successful, she didn't think much of it since she didn't believe it. She just felt Klaus was saying that to make her feel better.
