Aiden was on the tree, not making any sounds, waiting for the perfect opportunity to drop down so that he could find a place to go inside the castle.
Seeing the guards look away a second time, Aiden dropped down and started running while trying to find some type of entrance for him to go in.
'Just where can I enter this place? Don't tell me there's only one entrance.'
If there was going to be one entrance, then it would have been a big problem for Aiden since what he needed to do was go in without being noticed.
He was only trying to get information about who owned this place and who lived in it.
He wasn't trying to find anybody. The task he had given himself was to simply observe.
As he kept running around the castle, trying to find a window that was unlocked or anything that could help him enter, he perceived what seemed to be a garden.
