I think she’s the counselor Troi of the show for now. When Troi started she was mostly eye candy and sexual tension fodder for Riker. Chloe is fodder for Scott and Eli, but that can only last for so long. Then, Troi actually got Starfleet training, became involved with Worf and helped more with regards to ship duties.
Who knows, she could become Eli’s apprentice, medical assistant, or whatever. She has definite potential.
Or, they can kill her…again… ><
