What is Dorian's connection to Sybil?

Dorian Gray fell in love with Sybil Vane because she was such a wonderful

actress: he felt that she could really make Shakespeare's plays come to life.

However, when it occurred to her that it was wrong to mimic passion on a stage

when all her real passion was centered on Dorian, she lost her acting skills.

Dorian, after seeing this, went to her and declared that she had 'killed his love',

that he now found her 'shallow and stupid' and that he 'couldn't see her again'.

She committed suicide that same night. Eighteen years later, James Vane,

Sybil's brother, was accidentally shot dead while seeking revenge for her death.
