Jerome nodded slightly while inevitably thinking about all the people he'd met so far, and that most of them had been clearly younger than 40, safe for Oliver and Joe, unless they looked way younger than they were. He wasn't interested in Joe's age at all, as only thinking about that guy sparked the rage that he still harboured inside his heart, and he knew that he would have a hard time keeping himself together when actually getting to cross ways with him again, whenever that would be. Hopefully not too soon. But he was interested in Oliver's age, because, which could also be a side-effect of the cultural and linguistical differences, from Jerome's point of view, he looked younger than he acted. If he were to guess, he would say mid-forties.
"Do you mind if I ask your age?", he tried to satisfy his curiosity while finishing up the fumbling with the cake, then dedicating himself to the iced coffees again while eyeing the plates Oliver was preparing, which evoked a tiny grumble inside his stomach, signalizing him that sandwiches had been a fantastic idea after all.
When Oliver showed him the horseradish container, the coffee was finished and Jerome on his way to the sink again, as he turned his head to actually see what Oliver was talking about. "Horseradish" definitely wasn't something his vocabulary was able to offer, and he had to take a closer look to actually recognize what the contents of the container were. "I do.", he finally replied, smiling approvingly.
