There's when he questions the interns one by one at the end of season two, after Izzie cuts the LVAD. He questions each one one at a time, trying to get them to verify what he already suspects happened. That's the closest thing I can think of. If that's not it, if you can provide any additional detail, I'll try to figure it out.
