I'm sure someone has said this before but...
I think it would be really funny if Scarecrow fear-gassed Tim and just, like... nada. Red Robin keeps walking right towards him, no mask for the toxins, just breathing it in, and beats Scarecrow's sorry ass back into Arkham.
Crane is panicking: what went wrong with the gas? Was it sabotaged? Have the bats figured out how to metabolize it somehow? Is Red Robin not a human? What is going on???
Meanwhile, in the Batcave, everyone is asking Tim how he did it, and he's like, "um. I didn't get gassed? Like, I was having a trauma-induced hallucinogenic episode, don't get me wrong! I saw loved ones dying everywhere; Bruce hating me; failing at everything I do because I'm not actually smart, just lucky... the usual. But it wasn't Scarecrow's doing. That just happens."
And then a minute later he's like, "although that hallucination did have a lot of spiders in it... holy shit, I might have been fear-gassed."
