You said it is important to you to look after your teams. That is all well and good, I understand that. Since you had never met Ms. Daly before though, why did you think you were the right person to assist her when she was stressed and didn't want to take part in the investigation? You could have asked Mr. von Schoenberg or her direct manager to do that.
Don't you think you stepped up a bit too much when that was not necessarily what was expected of you? One might even think that you had received orders.
