The doctor and martha drive me insane because Donna actually told him to "find someone" and "sometimes I think you need someone to stop you" and then IMMEDIATELY he finds martha. And it's not like four and Leela, where after leaving Sarah he was content to ignore his loneliness post The Hand of Fear until Leela practically friend-trapped him in his own TARDIS, no, the Doctor WANTED Martha to be his companion, he actively gets her alone and tests her intelligence and thinks yes, she's the one. He doesn't even properly invite her after the Judoon leave, he comes back for her later that night. That's not him having a moment of excitement after an adventure, that was calculated
