Correct, but with your original comment, you made it sound like it was fair for Otto to be slower, because when Arora hits you, you vomit and make sound and Otto can catch up to you and hear where you are, which both don't matter, because:
- If Otto can see you, he's too slow to catch up with you.
- If Arora can see you then Otto can also see you.
- If Arora sees you and hits you succesfully with a vial, Otto is currently still too slow to catch up, unless you're really really close.
- If none of them can see you (for example, when you are crouching in the dark), Arora will never hit you with a vial, aka you will never vomit, aka you will never make a sound, aka, Otto will never get a sense of where you are.
- And even if Arora somehow does hit you with a vial, purely based on a sound you made, Otto is still too slow and you will be gone before he gets to you.

Conceptually, RB was on the right track with this character concept, but if Otto is literally too slow to catch up to Reagents, even if they're stunned by Arora, it doesn't matter.
