Oliver hadn't brewed potions in a few days so the air of the lab was rather pleasant for a change. He had been in quite a funk, and he wasn't sure why. He felt a little bit lackluster, worn out. Maybe it was age catching up with him.
Sighing, he went over to the bookcase and pulled out a copy of "The Last Crusade" a cheesy muggle science fiction novel he had found in a box at his parents house after they had died.
He sat down to read it, but quickly dozed off. At the sound of the knock, Wood jumped out of the chair, drew his wand -- from which sparks and a loud bang emitted, promptly pushing Oliver to the ground.
"DAMN IT," he cursed as he rose to his feet. "Come in!" He crowed as he dusted the dungeon floor off his pants.
