No one in the story is named Isaac. You'll get it by the end. Voldemort wishes a test of Lucius Malfoy's loyalty, and who better to test a man than his own son? One-shot. NOT slash.
Until the day he died, James would tease Remus and Sirius about an incident involving a theoretical mad house-elf, a pair of Peter's socks, and some mistletoe. MWPP one-shot. Slash? You decide.
