You could post IC that either Garamon searches for candle wax, or else that he simply grabs some candle wax from .... and tell me where he gets it from. If it's highly plausible and/or believable it will fly. Otherwise I'll tell you if it doesn't happen. Remembering that we are down to moment by moment action here, so... running upstairs to search for candle wax in the officer's quarters (for example) would take some time.
Yes, I guessed as much. I would hazard that fingers stuffed immediately into ears would be the best and most urgent ear stops. Searching and/or reaching for wax, then forming and fitting a pair of plugs, is not going to be quick enough should they being to sing.
