This differs a lot from the books, wherein Bowers and his gang chase the Losers through the sewers, only for Pennywise to kill Bowers’ gang.
In the first movie, the Losers’ Club is plagued by a trio of bullies, led by a devil of a kid named Henry Bowers.
Eventually, Bowers is seduced by Pennywise and sent to kill the Losers’ Club, but Mike ends up pushing Bowers down a seemingly bottomless pit into Pennywise’s lair.
Does this mean that he did end up in an asylum after all or will Bowers get involved in some new way?
