In the latest episode of The Flash, All Doll'd Up, we see Ralph aka Elongated Man swinging over buildings, throwing arms around like Spider Man does his web, while carrying Iris on his back. Just before that, he said he saw this in a comic book. It sounded to me like a tribute to Stan Lee. Am I right in thinking that, or is this just a coincidence?
I'm going to go out on a limb and say no.
Stan Lee died on 12 November, and the episode premiered in the US on 13 November. There is no way they could possibly have rushed out such an indirect, CG-intensive tribute in such a short space of time.
Most likely, the episode was written months ago, the scene is a reference to Spider-Man rather than Stan Lee, and the fact it aired only a day after his death is just a tragic coincidence.
