I feel that Sergei Semak is not the right character for home page. He did not appear in great deal of episodes and the only character he is actually significant to is Alex. He does not even have much impact on story.

What more there are two possibilities that I perceive as better choice. One would be Sonya. Her biggest advantage is that she is alive and there are therefore future possibilities for her to shine. Second character better than Semak is Ari. Nice touch since he killed Semak. But Tasarov is much more story-important and I would choose him over both Sergei and Sonya.
