 In season two, Mike Flynn asks for an electronics technician to be posted about Hammersley due to multiple errors, and ET is asked personally by Cmdr Steve Marshall to be transferred back to Hammersley.ET reluctantly accepts as he knows refusing to take a Cairns posting as he wanted would create suspicion, but Nikki is mad at him for not refusing and does her best to avoid even talking to him for several episodes.After a hostage situation aboard Hammersley (Takedown), Nikki starts to cool down as she admits she is happy to have him around, even though they can't be more than friends at that time.
