totally different relationship.
In the episode "The Most Unforgettable Characters", Hawkeye & B.J. pretend to be mad at one another as a gift for Frank's birthday, but after a short while the two of them are no longer pretending. Radar said it made him feel so sick seeing Hawkeye & B.J. arguing. I felt the same during this episode, as well as "Period of Adjustment" and "Preventative Medicine" yet whenever Hawk & Trap argued or fought, it didn't bother me at all...
I feel the same way. here's why.
Hawkeye and Trapper were friends, but that friendship was mostly around making fun of Frank, drinking, nurses, poker, and hating the war. Beyond that they weren't really that close.
B.J and Hawkeye, though, was completely different. They were the very best of friends. B.J confided in Hawkeye about "falling off the fidelity wagon" in "Hanky Panky" and writing Peg.
In "War Co-Respondent" after B.J walks into the Mess Tent when Margaret, Mulcahy, Klinger, Hawkeye and Charles were talking about what might have happened between Aggie O'Shea and B.J. He walks away in a huff, and Hawkeye follows. After a patient goes south on B.J, Hawk offers to help. After accepting it, Hawk is able to get B.J to open up about his feelings about Aggie.
There are others. None of these would've happened between Hawkeye and Trapper
