At the top of the watch tower, Talo sat and watched everywhere, his eyes scanning the ground below him. It was his job to watch for the monsters and alert everyone, so that everyone could be safe. He even had a goron helping him out just below. He hadn't been ordered to do it, he more or less just took up the job, same as the goron aiding him.
An incident like the one that had happened to Colin wouldn't happen again because Talo would make sure it didn't. No way, he was going to make sure he protected this village no matter what. New monsters were appearing all over the place and he wasn't going to let them hurt anybody around him.
Even if he couldn't be as brave as to jump in front of a charging beast like Colin had or go through Hyrule field from the castle town to this village in a cart with all matter of monsters attacking him like Llia and Telma had. He could still help this way. This was the only way he knew to help.
To him, That was really all the conformation he needed as he yelled a warning to everyone after spotting a gray wolf with some creature on it's back come into view near the village entrance.
