Yeah i to would like they remove poly, as i said previously, they chose two most damaged characters for poly, after everything SH went through (brainwashing, memory wipes, losing parents) i don't see how poly and sharing is healthy for her, i would think she would prefer stable relationship, especially as she stated in previous 2 acts that she is against sharing.
Also Halsin himself should see how emotionally broken/vulnerable she is, for somebody so old and wise.
