He's constantly praising Lucy and George. He's often the first one to try and apologize when he gets into a fight with them. The second he clocks Lucy as a "safe person" he becomes super touchy and holds her hand constantly. He compliments George's cooking. He's visibly proud of the people he cares about and publicly defends them on multiple occasions. He repeatedly asks his team if they're okay and tries to get them to open up when they're having issues. He makes an obvious, conscious effort to repeatedly tell Lucy he believes in her and wants her to stay at Portland Row. He smiles and jokes and laughs around with them on a pretty regular basis. He's also emotionally aware enough to tell Lucy "the reason I haven't talked about this subject with you is because it's relevant my childhood, which I don't like to talk about because it's pretty traumatic" when she questions him ahout Jessica's door, and he's kind of astonishingly open about his trauma with Lucy and George despite generally being unwilling to actually talk about the details.

And this applies to characters other than Lucy and George, too. He compliments Kipps' team during the graveyard fight and clearly respects Flo, for example. He's kind to Winkman's son, is generally polite to his clients, and is affected by the death of the undercover agent to the point of having a panic attack. It's pretty clear he cares deeply about the people around him even as he tries to push those closest to him away so they won't mourn him if (when) he dies.
