Sitwell and Hawkeye saw each other's helplessness in their exchanged looks, though the nature of it was somewhat different.
For Hawkeye, his helplessness mostly stemmed from Sherlock's "mischievousness." After all, Sherlock's little jokes were nowhere near enough to genuinely anger Hawkeye.
And with Doro in Sherlock's arms, Hawkeye, also a father, felt a measure of empathy. He naturally thought of his own daughter, and Sherlock became ever so slightly more pleasing to his eyes.

The essence of the conversation between Sherlock and Coulson just now had been a warning to S.H.I.E.L.D.—or, more plainly, a warning to Hydra to stay away.
That was why Sherlock had so seriously corrected Coulson's wording. He had come to help out of respect for Coulson, not S.H.I.E.L.D.!

As for why he had proactively exposed Doro, this "weakness," and openly introduced Doro to S.H.I.E.L.D. or Snake
