Inside the king's castle, in the throne room, Leo and the others had just heard the offer from the second leader, the original known as Tempus. The group didn't answer straight away. The truth was they wanted to converse with each other, but even if they did, it would be hard for them without Tempus listening to their conversation.
In a situation like this, Silver would often let Leo do the talking. She felt like this because they were the ones that were dragged into this mess in the first place, making her feel guilty. She felt like she had no right to make any decision on their behalf.
If they wished to try to fight their way out of this, then she would too. If they chose to accept the offer, then she would as well, but there was one thing she needed to confirm and get out of her mind because she didn't quite understand what was going on.
