Firstly, the Chekhov's gun theory I used to predict that Buddha will win and that therefore the next human would too.
If you remember after Jack's victory over Hercules, Zeus mentions that they can never allow the humans to take the lead
For those of you unfamiliar with the concept of Chekhov's gun here's the Wikipedia explanation
Therefore, when Zeus mentioned not allowing the humans to take the lead it was only a matter of time before humans actually take the lead.
The score right now is 3-2 for the Gods. With Buddha's win it will be 3-3. In round 7 humans win again, this time taking the lead. Again, I believe it's much simpler to have humans win twice in a row, rather than 3 or 4 times in a row which would have to happen if Buddha loses the fight.
Now it's 3-3. Qin wins making it 4-3.
Two times when the score was tied, the Gods took the lead. I think it's high time humans take the lead. Plus a Chief God losing opens up new possibilities. Like Beel taking over Helheim.
The way Ares is hyping Hades and Hades is hyped in general tells me Qin is gonna win. That line by Ares made me deffo think Qin is gonna win.
And the most important part. He came to pick them hoes up.
