On the other hand: Perhaps it wasn't the Doctor's friendship with Harry that (subconsciously) influenced him, but the fact that Harry was a bridge officer. Being one, Harry was - arguably - more valuable to the crew than Jetal was. Somebody should have pointed that out.
Can the Doctor have a subconscious? Should he have really been able to daydream and lose himself from time to time? He is a computer program capable of performing thousands of calculations a second (maybe). He should have immediately calculated that Kim was more valuable to the crew than Jetal without any issues.
