Flint looked at Roarn's reaction to the blow with relief. He nailed Roarn good and from how he was reacting it seemed the seastone was working its effect on him. This was good as it mean the overwhelming advantage the Logia user possessed was lessened. Of course, Roarn wasn't an idiot and also aware his big advantage was undermined in the presence of the seastone sword. 

"He's not getting away." He'd confidently say. Roarn was already trying to slip through the walls with his shadow magic. Luckily for Flint it was just right by the window. With sword in hand, Flint would try to beat Roarn to the punch again. This time by diving through the window. His sturdy frame would obliterate the wood and send glass shards flying.
