When we reached the Nightsong I just straight up murdered Shadowheart without hesitation. I then found out after reading online that she won’t actually kill the Nightsong if you just kinda trust her. All the good bits of Shadowheart are after that interaction so I left the first run thinking she was the worst, has a massive bump on my second run.
Still went through with the Astarion romance the second time
My first run I romanced Karlach.
