Poor baby girl....You have a good case, even without the witness.
Judges don't like people who take advatage of kiddies.
But the fact that you have a witness means Indra wouldn't have to testify if it goes to court. If this guy is smart, which is doubtful, he'll go to a mediator and at least cover the medical bills and damage to the scooter. Hopefully Indra won't have any lasting physical effects from the accident. *sending out healing vibes.*
