Ep 13, Just before Pete lets himself fall apart in Vegas’s arms (in the back of the bar), Vegas - seeing that Pete is starting to cry and won’t be able to hold on for much longer - gives him the slightest nod. A nod that says it’s okay, I got you, feel your emotions and I’ll carry them for you, just like I would with your violence.
For those who are confused with what is happening. I saw this post from a Facebook group. Source: https://www.facebook.com/photo?fbid=630899121746852&set=gm.1048887695686227&idorvanity=607999063108428
