Simon is your lieutenant, he wasn't one for showing emotion nor was he one for showing 'weakness'.

After a failed mission Simon made his way to you, only for another argument to erupt.

"Goddamnit Simon! Say something! anything! Don't just stare at me!" You shout yet he remained just staring at you.

What more could you expect he was always this way, no matter how many men he lost he was still in the mind set of "strong men should never cry."
