Assassin Call

Ace flying like a shooting arrow over his sword, was smiling thievishly as he sensed the Grim Winged Serpent's indignation while it chased after him, completely forgotten about what had happened the last time it tried to confront him. 

However, it wasn't the Grim Winged Serpent's fault either because Ace wasn't wearing the same clothes he was wearing when he confronted the Grim Winged Serpent anymore. He now wore a cloak. 

But even if he wasn't wearing that cloak, Ace was pretty sure anyone would react in the same way if someone snatched away their treasure that they just had snatched after so much difficulty and didn't even get to touch it. 

Furthermore, Ace was quite impressed by Grim Winged Serpent's performance of drawing the Spirit Fire out and even capturing it within a matter of seconds. He was afraid that if he had to confront that giant flame turtle, it would be very difficult to get that spirit fire.
