Rodney blurted:
a) You scared me to death, you idiot!
b) Of course I care!
c) I've been desperately in love with you since the moment I set eyes on you in Antarctica!

John stared at Rodney's unguarded face. He looked
a) somewhat pained, as if his underwear was chafing him in uncomfortable places.
b) like a rhino that was confused why the tree it had been running its head against was still standing.
c) like he had been desperately in love with him since the moment he set eyes on him in Antarctica!

Rodney groaned:
a) Oh, my god!
b) Ughn.
c) I've been desperately in love with you since the moment I set eyes on you in Antarctica!
