Met ray just now

He was just going to leave C block when I was trying to autoclave some dirty things. He said he'd show me the PCR after coming back (from holiday, of course). There was nobody at C block that time and, apparently Ray was going out for holiday as well (casual shirt and short jeans, carrying backpack)...isn't it still too early?! ...Wait! That means the autoclave room's also been locked and nobody would unlock the door for me this afternoon; how should I collect my autoclaved stuff this afternoon then?
