Helia could be a cool companion, not only was Helia a werewolf Halfing Bard, by going by Astarion's cut lines, he meantions her as Saucy, meaning this characters had a lot of sass and sarcasm to them, Larian knew which direction they wanted to take with this character, they had a plan and chose not to follow through with it, oh well maybe Helia can be salvaged up as DLC or as a patched in Companion.
