You and the group of losers went exploring in the sewers to find Bev, and Pennywise.

So much has happened since you walked in.

Bev was floating.

Ben kissed her to save her.

Bill shot Pennywise.

But..now Pennywise is holding Bill in his arms, ready to kill him.

The other losers are all holding you back, as you are absolutely livid, and looking like you're about to drown Pennywise in his own sewers.
