Grim had been training for a while to occupy himself, that was all he ever did before this mess. To be honest, He missed the distraction of it. He missed his heart skipping a beat as he was seeing if he hit his mark or not. The racing of his heart as he sparred, though not many would take him on.  His eyes looked Lucifer up and down, with the small smile he always had on around Lucifer. "Well, I'm hoping I'm not going to have to take a rain check on that."
