Question about Jekyll and Hyde?

the incident at the window reveals that, after the fact this is, that jekyll is now involuntarily turning into mr hyde during the day when before it was only ever at night while he slept or by his taking the potion. it is revealing the loss of control that dr jekyll has over both himself and mr hyde...the bad inside him is slowly taking over the good, and no matter how he tried he cannot stop it, the realisation that he will evetually cease turning back into dr jekyll and will remain permenantly as mr hyde!
