This Confirms Something.

He entered the academy as he was standing on the compound currently. And his eyes were scanning around in search of Lucia, she mustn't sight him.

Imagine if Lucia sets eyes on him, that would be plan spoilt.

'Is she on the compound currently? Or is she still in her classroom? Or has she headed home?'.

According to what Aiden was seeing currently, there weren't many students on the compound, many were still strolling out of their classrooms and reaching the compound.

There weren't many horses on the compound as well. It was only a few parents that had arrived to pick up their kids, some had ridden out of the compound with their kids already though.

..It hadn't been too long since it got to their closing hour.

Their academy wasn't the same as Aiden's, they don't close at the same time. So since there weren't many students on the compound yet, Aiden could easily glance around, and he didn't sight Lucia.
