I have three that come to mind quickly, but I'm sure there are many more.
The first is during Eagle Two when Spike is preparing to remove the collar bomb. Catherine Graham is concerned about Spike not wearing protective gear and our favorite bomb expert is so sweet and reassuring.
Second, during Follow the Leader when Greg and Spike take down the first kid with the bomb. Spike worries about Greg and his arm and Greg quickly reassures him. Then once he's ready to diffuse the bomb, Spike looks up to see Greg still there and tells him he needs to clear out. The look the two men exchange says so much without any words needed.
Another favorite is during Good Cop when Ed comes to give Jules the hoodie and phone. You can tell it's hard for him to let her go when he steps toward her and seems to stop himself from saying anything. I particularly like it because when see plenty of evidence of Greg and Jules' special relationship, but there's a lot between Ed and Jules as well.
