A decade in the special forces had taught him many valuable lessons, some he had been forced to learn the hard way too. Earnestly Grimm was all for not having to use the weapon on his hip. He hoped that the need never arose for the Marine to have to draw it in combat again. Reaper could completely agree that violence was a thing meant to be used only as a last resort, yet he knew first hand that sometimes a situation really did call for firepower and not diplomacy. Just a week and a half ago John had relied on his weapons to get through that hellish Mars base. Fought his way through the dead, and demonic like mutations as well, all to reach and rescue his sister Sam. Without the gun or his knife...even that inhuman strength of his would've only gotten the Space Marine so far. Instead of saying any of that though he merely offered a slight nod of his head when the Doc mentioned letting it go. It was clear that the two shared a lot in common, but on the matter of using a weapon John chalked it up to them simply having a different view of things.
The offer of the presented croissant brought the smile back to his lips, and without hesitation Reaper took a little bite. Chewing it with haste before licking his lips at last. "A dozen might be a bit much for lunch, but splitting a dozen between us as we took a stroll...now that could be a decent snack, Doc."
