clones having actually REALLY bad facial recognition if someone changes ANYTHING about themselves.
with the clones using their wildly different hair styles/dyes and piercings and tattoos to help differentiate each other. it becomes identifying features, and so they stick to those chosen looks forever.
which results in hilarious moments such as:
Obi-Wan, cuts off the mullet: hello there
212th, collectively raising their blasters: who the fuck are you and how did you get on this ship?
Mace Windu, coming back from a long and tedious time at the temple going over reports and strategies and redirecting senators with a scruffy beard: good morning Commander
Ponds, internally: omg omg omg when did they start cloning jedi? or has General Windu always had a brother? is this a test? is this an imposter?
Windu: I know, the beard is untidy, I was planning on shaving in my quarters once we were in hyperspace
Ponds: ... of course sir.
Plo, who's eye protection was compromised during the last battle and has to use his backup pair:
Wolffe: *snarling*
Plo: I will refrain from wearing the orange ones if it makes you that uncomfortable Wolffe. they are a bit gaudy but they were a gift from my niece.
Wolffe: ... buir?
Anakin, sparring with Ahsoka: damn its hot in here *puts hair up into a ponytail*
Torrent Company: *tackles Anakin*
Ahsoka: uhhh what?
Jesse, from the pile: don't worry Commander! we'll take care of this stowaway!
Echo: how'd this guy even get on board!?
Hardcase: I don't know but he must be stupid to try and fight the Commander out in the open like this- why are you laughing commander?
