You know, I would have wanted more Wally West during season 2. Greg disagrees, but I think his inactivity does cheapen his sacrifice somewhat. Based on Season 2 screen time alone, Impulse sacrificing himself would have more emotional oomph, especially if he pushed Wally out of the way, and took in a huge blast of energy that disintegrated him.

Then he can of course come back as Inertia.
