@Adendon 1: I don't think so - I think if a grenade rolls that far it's in.
2: Yes.
3: As far as I've seen - it destroys everything in the air once it's activated. While the ult is being placed/doing the startup animation things can still arrive, if you have bangaltore bombs around you in the ground already - the ult won't destroy them, it just deals with airbound things.
4: I've found abandoned Wattson ults after a fight has happened and then everyone has left and they still charged my shields. This sounds like a bug, it should just keep charging your shields.
5: No to bang smoke (I think), it doesn't destroy path ziplines either (I think) but it does destroy gib/bang/caustic ult grenades if they're thrown within range of it. It won't clear caustic gas from the ground. It won't destroy bang rockets in the ground if you place it after they've hit. The only ult it's worth place IN after it's been triggered is Gibraltar's.
6: No - no one can. If you try throwing grenades into/out of the ult when it's fully active (after it's warmup animation while the thing is extending/building) they just get destroyed in the air.
7: Yes.
Last thing worth knowing about her is that if you carry ultimate accelerants with you : you can place 3 of her ultimates side by side and it triples the speed of your shield recharge rate.
