It would be interesting if
- Slade seduces her and makes her fall in love with him and trains her to take down Oliver and Sara , Laurel is tied to both characters they both care about her.
- Laurel could wear a mask , I can imagine the WTF moments when they realise who's who.
Why this would work
- At this point Laurel has no one on her side shes vulnerable.
-Slade has already mentioned she is a big part of his revenge plan.
-Taking her away from Oliver and Sara would be the ultimate revenge as opposed to just killing her off.
- Plus it could Katie Cassidy something better than damsel in distress shes the only main character the writers have left to fix Roy and Thea are better this year .
