A pellicle is formed from the bugs, in this case Brett, forming a protective layer to keep out air. In my experience, it does not go away, but longest I have let Brett sit is maybe 7 months or something.
You don't need to worry about racking it over. I have drunk samples with bits of pellicle in them. Nothing to worry about.
If I were to rack this beer, I would remove the plug on the end of the racking cane and take the trub over along with everything else. The Brett will be happy having all of that tasty stuff to consume later on.
Thanks Matt. Thats the plan. I may peek inside the lid tonight and get a pic.
