Halloween 1981
I just realized something:
Not only was a pretty dumb of James to face Voldemort without a wand (let alone run around without a wand while being chased by Lord Evil™) but with a wand he would have had a better chance buying Lily and Harry time because he could have dueled with Lord No-nose.
No wand: Hi, I'm Lord Stupid-name. Avada Kedavra! *the end*
With a wand: Hi, I'm Lord... *curse hits him in the face* *in the background you see Lily and Harry fleeing with a portkey*
