Sydney cant fly, bubble and use the light hook simultaneously. Flight and shield are necessary for any particularly long distance transport, so anything she is carrying is loose inside the bubble with minimal restraint. If she's using the light hook and flight, her max speed is very limited. If she isnt flying, then she's walking, ergo she should be fit.
Also, i will repeat, since you seem to have missed it, what does she do when winter comes and she needs to wear gloves out doors? Suck it up and end up in the hospital with severe frostbite?
