I was thinking that he'd arrest Neil due to discovering he wasn't with Dru like he said he was thus he lied and that combined with the other evidence (Neil's DNA found on her) I'm thinking its Neil....but we'll know soon enough.
I think Jana has something to do with the art stuff/story, not Sheila but who knows.

I remember way back when reading that Jana's cute necklace that Gloria admired is a recording device!!!
I wouldn't be surprised if Amber had something to do with Sheila but not quite sure yet. Maybe she'll offer to care for Lauren's baby and its really Sheila!! No idea yet though.
I highly doubt Jana is Sheila's daughter as they parted ways very negatively back on the Bold and the Beautiful.
