Maybe we will get Helia after all 😊
I'm pretty sure he's not referring to new origins, but companions like Halsin, Minthara, Minsc and Jaheira.
Best bet is Alfira who alot of folks were surprised was not announced along side Minthara and Halsin and my guess which might surprise you is The Guardian, Daisy which we make at Character creation and who is now a physical being we meet in chapter 2. She wouldn't be much of a Guardian if she lets us just run around with him/her/they.
