Opponent at pre-defense as well

Four months ago I noted that I would be appointed as opponent at Mara Woods' defense of master degree. A few days ago I was asked to be an opponent (one out of two) at her pre-defense as well. This pre-defense will take place in the week July 11-18. I have earlier confirmed that I will still be the opponent at the defense which has been rescheduled for August (it was originally scheduled to take place in the very end of May).
