A Station Eight Fan Web Site
I was a huge fan of Young Justice when it was on air, and would even manage to wake up for it on Saturdays (Specifically for season 2) despite being a college student who loved to sleep in.
I especially loved Wally's character, and felt that he was the best character (With Robin/Nightwing being not too far behind with his constant prefix questioning)
My question is, which do you think caused the most people to react to Wally's sacrifice at the end of Season 2? The attachment to this specific Wally that you guys built up over two seasons, the fact that your Wally was the only remaining Wally in media at the time (As it would be a while before he was added back into comics), or the end of the show meaning that we might not know if he could ever return.
And heck, I'll add in another question. What was the inspiration for Dick's obsession with prefixes, and why he chose to use the non-prefixed words? Specifically Whelmed because that was always my favorite.
1. I can't speak for the fans. It sounds like all three of your suggestions played a role.
2. As I've stated many times before, Robin's "unwords" were inspired by actual conversations I had with my kids.
