Lancer raised an eyebrow at first, but his look transformed into one of understanding as Valerie came up to him and offered him a necklace. Already, he could tell with a glance that there was power within it, most likely soaked within the structure of the gem in the form of Mana waiting to take the form of a magiological effect. He reflected her grin, carefully accepting the item out of her hands, and clutching it in his right hand. He briefly considered probing into the spell system embedded in its very structure, but decided that he could do so later, probably while he was out and scouting. "Don't worry." Lancer said, chuckling slightly, "What kind of Servant would I be, leaving my Master as soon as the War begins? I'll consider this to be a good luck token, at most." Still, he dutifully made the display of tucking it neatly and nicely in one the frontal pockets of his jacket—his left pocket, to be stored near his heart. If anything, that action made it clear enough that Lancer took Valerie's precautions seriously. "I'll do my best." he said, and with that ending note, he turned around and began walking away, towards the door. It was in this moment, with a clear view and good illumination, that one could observe the strangeness of Lancer's cloak: the wavering was not an illusion or trick, but was in fact the cloak itself seemingly flowing into adjacent space to occupy it, as if it was some kind of immaterial liquid that somehow maintained a consistent form. Although it definitely had a physical presence in the way that it was worn by Lancer, nothing suggested that the cloak was actually made of something tangible... or even composed of ordinary matter. Was this his Noble Phantasm? Lancer stopped by the doorframe, a motion that suggested that he had in fact something else to say, or do. Or both. "Ah... I almost forgot. You gave me this necklace," he told her, tapping his breast pocket for emphasis, "so I'll give you something in return." Having said this, Lancer reached into his cloak, his hand practically disappearing within the black material, and making it quite apparent that it did not conform to the laws of space as they were commonly seen. Within seconds, he retrieved a small object—the distance plus size making it difficult to discern what it was in Lancer's hand—and, with a smooth motion, he threw it in an arc for Valerie to catch. "Somewhat of a Noble Phantasm that doesn't belong to me, I suppose." he explained, his expression fairly unreadable, "It was given to me long ago by..." he trailed off, shaking his head, and quickly resuming, "Well, it's something I have no use for anymore. I was intending to give it to my Master from the beginning... so, it belongs to you now." Lancer concluded with a small smile. It was an innocuous, ordinary-looking red pouch. "I'd explain what it is," Lancer said, turning back to face the doorway, "but it's fairly straightforward, really. I'm sure you'll figure it out in no time, Master." With that and a small wave, Lancer stepped out of view.
