Ether is showing strength to you people because you think he has been so underperforming? What do you expect from altcoins if they will not underperform.
I will not be surprised if bitcoin falls, ether will fall with it but ether will fall more than bitcoin. Did you noticed that as ether is over hyped recently, it will increase than usual but later everything still balance.
If ethereum falls, it might fall right to its end. It might never recover back again but if bitcoin falls, it will recover again and again. I know this because we have seen bitcoin do the same thing while a lot of people grow worry about ethereum. The second spot to bitcoin might open up soon.
