He can tell other people what he likes about what happened but anyone with any ounce of integrity will see through him (especially it they know him) and the truth will out in court. Don't dwell on what other people might or might not think. Something I always say to myself is " We wouldn't worry what other people thought of us, if we knew how little they actually did."
So whilst you are thinking about the repercussions of his lies, most people actually aren't that bothered. It's true!
This man is a psycho- hosebeast and you need to avoid him, keep your head down and don't be goaded by anything he says in court.
Be glad that you found him out.
