Drafting a Missing Scene

At the end of Act 1, Scene 1, Helena decides to tell Demetrius about Hermia and Lysander’s plan to run away and get married, but Shakespeare keeps that action off-stage. Your job is to create that missing scene between Demetrius and Helena.

How would Helena deliver the information to Demetrius? Would she tell him straight out, or would she try to bargain or strike a deal with Demetrius for her information? You might want to include how Helena is feeling, how she knows this information, and why she is telling it to Demetrius.
