Harry thought to himself how to escape, these were his thoughts.
1. Touch a Sister's hand, knock her out, take her robes and exit unnoticed.(Leaves a body and you will be found missing).
2. Touch a Sister without her noticing, take spare robes and leave.( You will be found missing).
3. Try and attempt a full body swap. You become the Sister and she becomes you. (Can very dangerous with heaps of outcomes).
4. Become an adopted Orphan due to be picked up tomorrow (The orphan is blind and deaf).
5. Attempt to run for it (stupid).
