So if we discount little girl being a fragment of wendis. Little Girl resembles a younger Robin even when talking to Yarra during the Erosian crisis assault on headquarters, whether this is Sierra just using one model as a timesaver, the resemblance is entirely coincidental, or she's mirroring Simon's impression of a "daughter" even when not talking to him, that is the question

Given she's latched onto Simon i'd guess option number 3.
