I was all set to watch that and mount a spirited, tongue-in-cheek defence of the platonic friendship nature of whatever it was and rant about the kind of people who devalue close friendship by e.g. claiming Frodo and Sam are gay and so on . . .
Amusing trivia: Ian McKellen, who played Gandalf and who is gay if you weren't aware, is largely responsible for the scene in Fellowship of the Ring where Frodo has been taken ill or has been injured or something, and wakes up in bed in Rivendell. When he wakes up, Sam rushes over to him, says something about how happy he is to see Mr. Frodo, and clasps Frodo's hand in both of his own.
McKellen recommended to Elijah Wood and Sean Astin that they play the scene like that to show how deep their friendship was.
And then a year or so later he ponied up and admitted (with a twinkle in his eye) that he was actually trying to inject a little homoerotica into the scene.
well that kind of hetero friendship was the norm in america during WW1
in one of the boukengers after episode extras bio yellow and bio pink have a heart between them and bouken yellow flirts with boukenpink while boukenpink is grossed out with yellow. IN Doubutsu Sentai Zyuohger there is Zyuoh Shark and Zyuoh Tiger both females making it a reference to tachi and neko yuri roles.
