'What is this?'
At first, Leo thought that he was really being attacked by the invasive influence of Shadow Mastery in an attempt to purge all thoughts of possible puppetry.
Fortunately, this was merely a product of Leo's very rich imagination.
'This is my own memory?'
The 'new' input was most definitely Leo's personal memory. However, the angle through which he perceived it seemed to have completely changed.
On that fateful day, he wasn't looking around in amazement as he observed the streets of the new world that he had just descended upon.
Instead, he was immersed in someone else's painful memory, a tale of burning effort that led to nothing but failure. Something eerily similar to a story that he had just heard.
'No, it's not just my memory… These are hers.'
As long as he wasn't under the effect of some kind of hallucinogenic ability, these visions could only be parts of Kara's memories.
