Having expected the mention of their arms to form some discomfort, and noticing their disinclination towards his approach, Lukas simply answered the peacock boy's question with a short and silent nod. He was not there to bother anyone, too much, and their shared burden warranted a consideration of privacy. Lukas never judged anyone for wanting to keep their cards close to their chests. Lukas had grown up in a 'don't ask, don't tell' type of military. Still, what he had been trained to learn underneath all that, was who carried an Arms Master, of any kind, so he'd know who to push ahead and who to throw aside. As this was not his goal at the moment, which he still needed to get used to, finding safety in recon was a hard habit to break.

He didn't make himself important enough to actively disrupt their conversation any longer, but remained in the warm sun, which he started to like more and more, listening to them. He smiled amused at the story about LARPERS and the tragedy involving monarchists, showing an easy going attitude towards global conflict, and a sort of confidence in his own role in the world. His smile naturally died down at the end however, as he did not truly find joy in the horrors of humanity, and did not want people to mistake that about him either. 

The peaceful raven hair kept his hands relaxed in the pockets of his blue jeans, and looked expectantly at the emo kid to his left as he was asked by the iranian prince boy what he preferred to eat. Lukas was pleased about the easy entertainment he got this early in his role as volunteer, whatever that meant.
