I remember my multi FI turning several interesting colours after he failed one of the engines at the start of our crosswind turn during assy circuits. The 'dead' engine was the inside engine and I was too slow to get full rudder in. Unsurprisingly the a/c rolled into the turn very quickly, and at 600' or so with a climbing a/c and dropping airspeed, being at some 60 - 70 degrees of bank and increasing I can understand his discomfort.
Happily, he caught the a/c a fraction before me and all turned out OK, but my flying buddy in the back was white for weeks.
