Wow is Sir Patrick Stewart really that tall, or are they just short?
Also, considering that loS2 is literally LoS 2, a sequel to the original, which was just Gabe for the whole game with that bit of Laura at the end in the DLC, I wouldn't be surprised if it's just Gabe again. With perhaps an Alucard mini-presence like Laura's.
or just Gabe, with Alucard a boss. (mite b gud)
MoF got away with multiple characters because it was a "side story". Gabe was not the main character.
