As a running gag, Kallen ends up nude or immodestly dressed in front of other people on numerous occasions: Lelouch sees her naked after she accidentally pulls back a shower curtain in the third episode, Suzaku sees her bathing under a waterfall when they are stranded on Kamine Island, she is forced to dress in an immodest bunny costume at the start of the second season (to plant a tracking device on Lelouch), and she walks in on a meeting between C.C. and the Chinese ambassadors wearing only a towel when intending to complain about the previous situation to C.C. (claiming that the operation would've gone faster if C.C. was wearing the outfit).
