I think if they had ran across the platform instead, they'd be going in the opposite direction of where they had to go to and could possibly end up running out onto the street and into another gang, then they'd be in real trouble. Swan would have to give them Mercy as a sacrificial peace offering, but with everyone after the Warriors that probably wouldn't help even if she looked like Cameron Diaz.

I agree with you though, if I was in that situation it wouldn't be my first instinct to run into the tunnel, not so much because of the rats, but because of what happened to Ramo in Beat Street.

It's quite tense that bit, more so when you first see it, probably because we saw Fox die on the tracks earlier. I do think that Swan was very street wise though and knew how to run into the tunnel without getting hurt.
