A tiny, amused chuckle fled Jerome's lips when Oliver replied, and he couldn't deny that it still felt relieving to have some distraction other than indulging himself into whatever kind of work needed to be done, or, didn't need to be done but was done anyway. He knew that there was at least one more serious topic he wanted to address somewhere along the lines of this lunch, and right now, he wasn't really in the mood to dwell on these things that were still nagging in the back of his mind since he had learned about them, but regardless, for the very moment, he felt better.
Better and for some reason, very thankful. Even though he couldn't deny that it did feel a little off that this was their first conversation in person after what had happened the last time they had seen each other, when both of them had kind of lost it in quite different ways, both in no condition to clean up the kitchen afterwards which was, presumably, a pretty big deal inside the house. Understandably so, if They really did punish people for leaving a mess behind. It didn't feel like they necessarily needed to address what had happened there, absolutely not, but at the same time, it felt as if there was a little elephant in the room, maybe because Jerome, obviously, still wasn't used to these crazy things happening around here, and the whole scene that had played out there, about which he hadn't talked with anyone yet, still felt like a pretty big deal.
But as much as he wanted to address this matter, as much as he felt like he needed to talk about it, something inside him didn't want to. Maybe just not immediately.
He watched Oliver as he checked the fridge and the shelves, grabbing the hose again to continue his dishes, still smiling amusedly. He would have been okay with a tarte au chocolat lunch for once, mostly because he still wasn't too comfortable with getting his food prepared for him, but actually, he did prefer a savory lunch after all, and there was a reason why he had never allowed his children to just eat cake for lunch or dinner.
"And how exactly will eating a sandwich and cake after that make you less fat than just eating cake?" He smirked a little, but nodded in response to Oliver's objection to his own playful suggestion, having turned back to the sink completely now and only turning his head in Oliver's direction again when Oliver did address him, which left him slightly puzzled for a minute he needed to process that Oliver actually was talking about sandwiches. Or at least he thought he was talking about sandwiches. ... It was probably best to just ask. And he really needed to grad a dictionary when they were back at the mansion, if there would be one in the library.
"We are talking sandwiches, right? I actually never eat them at home, so I don't have any preferences. But I'm not a picky eater, so everything is fine." Which wasn't a lie, but if he would really think about it, he would come up with some preferences, but Jerome wasn't fond of the thought of inconveniencing Oliver with specific food wishes.
