The Body before Frozen Veil?

[oath5]

I never made it to the ice cave yet, I got there, I just decided to turn around and leave since there was other stuff to do- now however I've gotten Li stuck in the parasitic sac bubble and I'm wondering is there an opportunity to leave The Body after saving Li before heading to the last boss or something?

I hate posting petty little threads like this, but I was just wondering if there is an option or has my path become moderately linear from now on?

The only point of no return in the game is once you enter the final boss chamber.

So, yeah, you can save him and go back.
