One of the most shocking stories Khan had ever heard reached his ears, confusing him so much that he was unsure how to feel about it.
Khan had picked up clues during the previous short interactions, but the whole truth turned out to be far more surprising than he could have ever predicted.
To make things worse, Khan didn't know what he found more shocking. Rodney hadn't only saved George's life twice. He also seemed to be serious about Monica.
Normally, Khan would dismiss that as Rodney's plotting. He was that kind of asset in the end, capable but extremely annoying, which Khan would usually straighten out with one of his threats.
However, the details George disclosed went against that bias. For all the loud, annoying words, Rodney truly seemed to value George's life more than his own and did indeed harbor genuine feelings for Monica.
