Oooo... That's some blue light there... might not be an ambulance.
Yay Tober! Stay healthy, and thank you for the updates

Uh oh! Did they slip onto another whorl? It looks like EMS uses red and blue lights in Auz, Eric. (For non-USAians, it's limited to police in several US states.)

YAY EMI!
Dispatchers here generally send a police unit to emergency calls anyway, so blue lights are no surprise. Memnon may be a bit of a surprise for those EMTs if he sticks around...
Thanks, Tober!
