Chloe (Chole) is the new guy on the Star Trek away team.. you know isn't coming back.Wait, wait... So, Palin scapes and gets reinstalled, but still we get another Engineer, Chole Sedesi, who, so far, does exactly the same as Palin in Engineering tasks... It is like if Sedesi is a safeguard... a redundance... just if someone will die suddenly and we need someone to fix our thrusters if one of them both die...
