Why do the giants in Shingeki no Kyojin start to look like the characters that got eaten?


In Shingeki no Kyojin, Armin's grandfather dies when he is sent to recover
Wall Maria. And in the episode when Eren gets eaten, the face and the look of
the giant who eats him is exactly the same as Armin's grandfather.
