When Beans has another of her zone outs during the posse's Darkest Hour, Rango tries to encourage her and he can't resist giving a peck on the check of the lizard he's growing to love. As he turns to leave, Beans returns to consciousness, apparently aware of what Rango did and smiling privately.

Rango exposed, going back to find the fish and hug it had this troper going melted.
When Priscilla, the near emotionless Eye-eye girl, embraces Rango at the end and says, "Thank you. You brought the water back."
Beans kissing Rango when they're in the drowning tank after excitedly saying "You came back!"
An atypical example, but Rattlesnake Jake showing his sense of honor and acknowledging Rango as a real hero at the end.
