It must be a timing thing, I have a feeling they will appear out of know where and do something to prevent her from creating another manifestation of her will while being sucked in to the seal too. Dam i did forget about them lol

They could get there through Hirashin, the pile of Obito has Tobirama's seal so they might join the fight. Minato said it never goes away and cant be destroyed so it should still be there.
