Hi Guillaume,
It's good that you're checking - shows that you care about giving your partner a fair experience!
Yes, you do need to prepare for the case that you are going to give. If you have solved any case already (ideally you have), use the one you liked the most. You need to make sure you fully understand the case, and can answer any questions the interviewee has.
If you have not yet done a case on your own, and don't have cases, you need to cancel the session until you are more prepared.
For Cases
There are a lot of cases here: https://www.preplounge.com/en/management-consulting-cases
