"I think you're in a bad mood and they're not that bad." Oli smiled softly at Percy. "I think if you tell them you want to keep your job, then they'll let you. Unless there's somewhere you're really needed." Oli was friends with the twins, not nearly as close as he was with Percy, sure, but he didn't think they were bad guys. Of course from Percy's standpoint, Oli could understand his worries. But sometimes he wasn't sure if Percy's suspicions towards his brothers weren't what made them pick on him so much.
"A mediator?" Oliver thought back to his recent conversation with the Weasley siblings and wasn't so sure if he could be all that helpful. If he had to take sides, he was definitely going to side with Percy. "I'll do my best," he said, meaning it completely. "I've tried. But it's good to know that I can keep up with you." A smile tugged at Oli's lips. "I'm really glad we got back in touch after the war, you know?"
