Twice. He's gotten emotional twice in our seven years and both had to do with deaths.

That's about all I'll say on it. In general he keeps it out of the room. Once he was caught off guard, I triggered him and he didn't expect it. The other time had to do with a health issue I was aware of from a brief conversation that had led to an unexpected death in his life. The triggered one set off a strong emotional response. The second one, he was clearly affected but redirected and reigned it in. You work with someone long enough things pop up.
