I first read CoC as Castle of Chess, lol far to many hours on mmorgps.
Anyway... if this has anything to do with Tasuku..
If referring to Tasuku's message to the captain, I guess it might be a little out of the chain, but that didn't cross his mind at the time, since it was a response to a general message he received from her.
If referring to his message to Hamada, he would have first contacted the supply officer, except that he (Roscoe Voe) never arrived IC, and afaik the roleplyer (Fay) is still completely absent from Star Army, yet her character has appeared on the Eucharis roster for some time. In any event not being able to bring the topic up with the supply officer, Tasuku assumed the second officer would be the one to bring the topic of power armor up with, since she had the listed duty of 'away teams'.
If either Hanako or Hamada feels Tasukus msgs are even mildly inappropriate, I have no problem with them bringing that up, the more rp the better lol.
Then again I have no control of other CoC issues such as an ongoing antagonism between two science personnel of differing ranks. :?
