Everyone who knew Jake personally was shocked after seeing him in such a battered and weakened state.
Even Ethan was deeply shocked.
Alex had asked Ethan to stand guard on his door all night long for the past two nights, and he even kept bringing Ethan around with him everywhere, as he didn't want Ethan to go home.
If Ethan had gone home, he might have gotten swept by emotions and might have helped Jake, as he couldn't have seen his son in such a terrible situation.
Thus, Alex kept Ethan close to prevent him from seeing Jake's condition.
Thus, Ethan was shocked when he saw Jake in such a bad condition, and it took him a lot of restraint to grit his teeth and stay silent.
He himself taught his son the code of honor, and thus he couldn't possibly get in between Jake's fight and try to help him.
Ethan was duty-bound and had no other choice but to stand aside and watch the duel happen.
