The judge told us, "If you want to meet with me privately to discuss issues you'd rather not discuss publicly, I will meet with anyone."
If you're at all concerned, talk to the judge in private. Maybe the judge, the bailiff, and you could work out a sign indicating, "I need to go, now." Judge can declare a recess anytime for any reason.
