As aside, hope Polly doesn't leap in to help Bern and get killed redshirt style in order to give Bern her motivation to win.
That's actually kind've what I expect to happen in a way. Warden just said that bern getting sexed would give her a hatred for the coliseum, a hatred she'd hone into a blade and become an unstoppable warrior. Something that polly only helped dull further.
I reckon the fight is going to start and either polly, or berns father are going to step in and get cut down in front of bern at which point we'll see some kind of magic empowered super saiyan bern with whirlling swords of death and destruction.
And considering the point system they use for this, kill 3 s ranks, in a single battle, I imagine she'd rack up the points pretty quickly, and if she is that powerful they'd probably start hurling her into more slaughter matches, many of them vs one of her so she'd be paid off silly fast and out of there in no time.
Just my hunch (she can't stay in there forever after all)
