Certain scenes from Toxic featuring Ticket convinced me of one thing despite what the climax is trying to suggest

So the climax of Toxic tries to tell us that Ticket actually never got saved by Raya and indeed drowned to his death. Every deed that Ticket seems to commit throughout the movie is actually Raya's doing. Not only was Raya hallucinating the grown Ticket but he was also suffering from split personality, which causes the Ticket persona to take over Raya at times and in such a state goes on a killing-and-destroying spree, thus making Raya's hallucinations seem real. The movie basically is trying to tell us that the Ticket we see is the personification of Raya's own guilt of all the mistakes he had committed as a youth, including his inability to save the young Ticket.

But what if the matter is not that simple? Mental trauma is a thing where the lines between reality and imagination go blurry, in which case it becomes almost impossible for people to distinguish them both. The same thing happened to Raya. His visible anguish by the end of the film was so great that it made him question his memories. And because he was in such a terrible state, it is difficult even for him to distinguish reality that appropriately while sorting out his hallucinations. What if while sorting out the follies in his memories, he ended up dismissing some of the "actual" events from his past as hallucinations as well (including the one where he supposedly saved Ticket from drowning), and by doing just that he convinced himself that those events never happened?

Normally this thought would never come across my mind, and the climax is pretty interesting to just negate it, but there are certain scenes featuring Ticket that seem to be too real to be just a fabrication of Raya's already disturbed mind. Especially the scene which shows him massacring a group of his own fellow assassins. Imagine Raya, with his Ticket persona active (his physical appearance wouldn't actually change with split personality), just there among the group of assassins who were actively targeting no one but him all this time, and none of them actually questioning the presence of their target within the jurisdiction of their hideout, that feels quite weird. What's interesting is that this scene is not a part of the montage of hallucinated scenarios that get replayed in Raya's mind in the climax. This particular loophole in the whole split persona-hallucination storyline written for Ticket should give us a benefit of doubt, that maybe not all of Raya's memories of Ticket are actually hallucinated/fabricated/imagined. Maybe Raya did manage to save Ticket that day, or probably (also less likely) Ticket himself managed to escape out of the drowning car soon after Raya abandoned his rescue attempt.

Anyway, since the movie has been critically panned by critics and its commercial performance till now has been quite poor, chances of a potential sequel are uncertain. So debating on this is probably just me wasting my time.
