The Tenth Night [Action]

 [To the surprise of no one, Batman has been hard at work in his room with a series of chemicals and scientific equipment.  Next to him are several pieces of equipment, but prominently are the little spheres he usually stores smoke in.   He appears to be tooling with creating compounds to go into them, if you're scientifically minded and in his house.

However, Batman's left his door open.  This is probably unusual.  Housemates, you know you want to bother Bruce while he's hard at work.

Of course, Batman wouldn't be Batman if he didn't go out on patrol when night falls.  He'll be floating around his usual haunts on patrol, not really expecting to find anything wrong.  There almost never is.  But old habits die hard.  Maybe someone will catch a glimpse of the Dark Knight tonight.]
