Sinestro was rather disappointed that he and his twin had been removed from the host club simply because Jeremy was going to have important guests over.
The fact that he couldn't be in the club wasn't the problem, this wasn't the first time that something like this happened.
The problem for him had to with the fact that Liam was able to stay behind while everyone else had to leave. Sinestro and Dexterous were almost in the same position that Liam was in. He only was ahead of them by a small smidgen which they would eventually close. What made him so special that he was able to stay behind while they couldn't?
He wanted to ask Jeremy this, but his brother stopped him before he had a chance. He didn't think that it was the right time to start a fight when the manager seemed rather stressed out over what he was trying to get ready for.
