Lunar walked into the main room of his part of the house where Castor and Pollux were sat bundled up in blankets holding a tray with 2 bowls of soup..

Lunar: so do you two have any idea how this happened..?

Castor: we are not sure.. sniff Pollux took us for another tour around Earth and the next thing we knew we felt awful.. we didn't even know we could get sick like this..

Pollux: sniff what is happening to us! I feel awful!!

Lunar: you have a cold Pollux..

Pollux: you mean that common Earthly virus!? this is what common Earthly viruses are like!? I've underestimated Humans!!

Lunar: you'll be fine Pollux.. I'll be taking care of you both.. a cold isn't hard to treat..

Castor: that's a relief.. cough cough!
