bear never tells ian sarahs died.

he runs to ians with his second one wish willow after realising he cant have another wish with one thought - get ian to make a wish that contradicts his wish (though we have no evidence to suggest that would work - the customer service rep says the only thing that breaks the spell is death) and he focuses his whole spiel on trying to get ian to make a wish, never once says even "nikkis just killed sarah"

because then hed have to get into why he was meeting up with sarah at 3am alone. why sarahs death was his fault - he knows that, nikki told him that. he doesnt want ian to know that. hes still trying to save face after ones of his friends was brutally murdered because of him
