Neji dashed up the steps to the doorway but did not open it. This might be Uchiha Sasuke, and it might also be a clone or henge of some sort... both possibilities meant that this situation had just become more dangerous. Even if this was the real Sasuke, he was a rouge ninja... he would probably assume that any Konoha nin was out to capture him, and attack them. If it wasn't... well the foyer was completely empty apart from the figure lying in the water, and this meant there was no point in being stealthy.
And so Neji gathered his chakra within his right hand, releasing it all at once as he struck the door. It swung into the inside wall with a loud THUNK that echoed around the foyer. Neji rushed inside, prepared to defend or attack as necessary.
