"There was something somebody affiliated with the project said (can't remember exactly) that indicated Sue and Johnny might not be brother and sister."
If they are not related then logically we should see the playboy Johny Storm hitting on Sue at some point. If she doesn't go for him he can tell her...
"C'mon Sue, its not like we're related or anything"...Then Michael B Jordan can look directly at the camera and wink.

And there should be a little *ding* sound when he winks.
At that point Marvel can officially begin thinking about how to best incorporate FF into their Marvel universe because Fox will have completed their failure.
