I do not think it is a good idea to allow a juror, during the course of a trial, to seek outside guidance in relation to the stresses they're having in performing their duty. That's one reason judges may have alternate jurors handy in a major case.
The magic of the jury system is that they are able to gather, almost as a family, protected, to make their deliberations. I didn't know that was done in Alberta, but I would like to look into that a little more. I think it's very dangerous to do that. If someone is having difficulty and needs therapeutic assistance as a juror during the middle of a trial, they're going to have difficulty performing their task, and they should be excused.
