Forum:Tali Loyalty question

I couldn't find any specific informaiton on this on either the suicide mission page or any of Tali's pages..

On the suicide mission page it says that it is possible for non-loyal squad members to survive if they are carefully positioned in the squads, and I was wondering if it was possible for a non-loyal Tali (as well as every other member of my team, who are all loyal) to survive; and if so, under what circumstances?
