Oliver wanted to point out that, if Dom didn't know, she clearly hadn't been very involved. But he needed to be polite and stay on topic. "I stepped down a few months ago, but was recently asked to come back. I haven't.. Well, I haven't made it public knowledge for a reason. I have someone to protect and I'm sick of the Order being so blunt about everything. What we do is not up to anyone outside of our group. And if someone can't be trusted, they shouldn't be involved. So no, it's not surprising that you didn't know I was back."
Declan was slightly surprised by the sharp bite of Oliver's tone, but he felt that maybe he was catching a glimpse of the determined, possessive side of the former Hufflepuff. Whether he would make a viable leader, Declan had no idea. But it was obvious that Oliver was trying.
Of course, as soon as Dom was able to get her tongue around the words, someone confirmed the problem and made their job that much easier. A look that Declan could only describe as contemplative crossed Oliver's face after hearing the woman's voice and registering that Dom's words made sense. Both of theirs did.
"Okay. I'll answer her in a minute. First things first," Oliver said, looking at Declan. "You aren't in the Order. Which, believe it or not, means that you could be of great use to us. You hear just about everything in that pub of yours, and I can promise you that we'll keep you safe if you decide to help us."
"I never- that is, I know my best mate is involved but I never really wanted to be," Declan said slowly, trying and failing to hide how cautious he felt.
"You wouldn't be a full member. It wouldn't be lying if anyone asked. I don't expect, particularly, that they will. Even with Dom around," he added, glancing pointedly at their hands. "She isn't known for being a member, so it isn't a problem necessarily."
Declan visibly considered this before squeezing Dom's hand and then nodding. "That's fine. I'll do it. But what are we doing about this train thing?"
Oliver frowned, leaning against the end of his kitchen counter. He was silent for a moment, simply looking at them, before he seemed to come to some kind of conclusion. "I need you both to know that I'm fully willing to Obliviate either of you if the following information gets out."
He paused, letting that sink in and watching Declan's eyes narrow defensively. Oliver caught the twitch in the older man's hand, likely wanting to pull Dom to him or to take up his wand. When he didn't do either, Oliver continued.
"I've been working with some students - ones who came home early - in secret. They told me that the exchange students at Ilvermorny have been unable to come back. Dom, I know you want to find out about your cousins but I need help. I need someone to take the ferry over there and tell me what's happening. If you're willing, you could be there by this evening and try to figure out how to send an owl back. One of the students I spoke to said they had a great deal of trouble communicating, so I imagine it won't be easy. But if we have eyes and ears there, Jack and I can turn our attention on this train. That way, when you get back, you can help us retrieve them."
Oliver shrugged slightly, pointing out that, "Actually, your staying would lead to days of doing nothing but waiting and fretting. At least, this way, you would have other things on your mind until we know more. But, as I said, no one can know I sent you. Not family, not friends, not the students you find. I'm not even sure if I'm going to tell Jack," he added for emphasis, not really meaning it.
All he did after that was look between the two of them, silently asking the question: Would they do it?
