How would have Vitali reacted to hayes trash talk?

After watching numerous interviews from both wlad and haye Im surprised how well wlad is taking the trash talk. He's laughing and joking at everything haye does. How do you think vitali would have reacted in this situation? Everyone knows vitali is the mean older brother who is your sterio typical ivan drago eastern block fighter. I for one think haye wouldnt push vitali as far because he knows vitali would probs explode in a press conference and break hae in half.
