I think it’d be funny if Dick and Jason, due to wearing bright yellow capes on the job for years, are capable of stealth to a frankly unhinged degree. They barely have to try anymore it’s so second nature. Dick can just completely disappear while in the loudest neon clothes imaginable. Jason is constantly startling people who don’t understand how they missed a guy the size of a fridge standing right there. Bruce is extremely grateful for his unbreakable poker face because they have both startled him by accident and would never ever let him live it down if they knew.
