Final answer:
Owl-Eyes blames the accident on Gatsby himself, which is ironic because Owl-Eyes is also a reckless character who crashes his car into a ditch.
Step-by-step explanation:
Owl-Eyes blames the accident after Gatsby's party on Gatsby himself. He claims that Gatsby is responsible for the chaos and recklessness that led to the accident. This is ironic because Owl-Eyes is also a reckless character who himself crashes his car into a ditch. So, he is placing blame on someone else for the very same behavior he is guilty of.
