'It's been a really long while.'
Having spent enough time in this new world where values were all over the place, Leo's nights had been getting more and more comfortable.
However, the lucid dream he had this time made it so this specific night represented the exact opposite meaning of comfort.
Leo ended up experiencing a big chunk of Cassian's tragic backstory!
'But…'
Although this part wasn't mentioned in the novel, the memories that Leo received dictated that this was practically a part of Cassian's existence.
Ever since he witnessed the blood path created by that psychopathic Hero, he would always see that scene at night in full detail. In fact, it would even contain things that he might have missed at the time of the incident itself.
Starting from the expressions on Fred and Naila's severed heads, all the way up to the killer's crazy smile. The blood-red painting was extremely vivid and so were the bottled-up emotions.
