He starts forward at that last cut, and his hands itch to grab Sirius' arm and yank it back - but fear holds him back. Fear keeps him from doing it. The sight of Sirius dead in his mural, dead by violence, and Edgeworth clearly responsible - It is most likely a taunt from the ship, and yet it's enough to stay his hand. Cowardly, he lets his friend do what he will.

And then, finally, Sirius is willing to go. Finally. Edgeworth feels ill, a little unsteady on his feet, as he turns and follows Sirius. Is he being foolish? Is he being irrational? He thinks about what an impartial observer would say about this - thinks about how the Miles Edgeworth of two years ago would view the Miles Edgeworth of now - and knows that the younger Edgeworth would be ashamed of how paranoid and superstitious he sounds. That younger Edgeworth would not approve of this vandalism, but from the perspective only of order and decency; he would scorn anyone who was afraid.

Then again, the Miles Edgeworth of two years ago was also a blind idiot.

All he can do now is hope that there are no consequences for this. That Sirius does not end up wounded or killed by the ship for his...insolence. Only once, only fleetingly, does he think to worry for Snape - and he'll regret that later, feel monstrous for the fact that his mind was only on his friend and never on his enemy.
