Yeah, the lore book is no help there either. In the book, Holiday is listed as an assassin whose specialty is vehicle-based assassinations. What that means is anyone's guess and it ends up raising more questions like:
- Why did Holiday specialize in something so niche? Why not poison or a gun?
- Why did Holiday choose to focus on a motorcycle rather than a spaceship? Actually, if she's specialized in vehicle operations, why isn't she the pilot? Can she even pilot a ship or is it just motorcycles she knows anything about?
- Why is Holiday on the mission at all?
- What is the usefulness of an assassin who specializes vehicles? Seems like it's a lot harder to be covert with a vehicle than, say, a knife.
- Seriously, what does it even mean to specialize in vehicle assassinations? Does that mean she runs people over?
I think that couple minutes of thought is more than what Brianna gave to Holiday as a character in the entirety of Rev60's development cycle.
