The original question had to be edited. I would suggest that Bruno's most essential realization during his interaction with Pavel was that what appears to be on the outside might not be reflective of the truth. Bruno thinks that Pavel would not be able to administer medical care for his injury. He thinks this because he sees Pavel as a servant. Yet, when Pavel tends to Bruno's injury it becomes clear to him that things are not what they seem to be. Bruno learns that what might seem to be true could have more under the surface. Another part of this realization centers on Lieutenant Kotler. Bruno already has a low impression of the Nazi soldier. Yet, when it occurs to Bruno that Pavel was so selfless in tending to him, it makes Bruno dislike Kotler even more to realize that treated him in such a harsh manner. This becomes another part of his realization about how life is in "Out- With" and his reaction to it. For Bruno, the fact that Pavel is more than he seems help to enhance the idea that there is more than what is presented to him. It enables him to gain some insight and reflection into the world around him and his place in it.
