There was a girl Yoda named Yaddle in The Phantom Menace. I suspect this one is a boy, though.
When was this? Or
which was this--book or movie? I completely missed it!
Anyway, they've been very careful to keep saying "it," so far, so I still think it could be a she. (I have to say, though, is it actually going to matter to the story?)
Maybe the more important thing is that no brother are left to fight alone. To the Mandalorian’s that has been the thing for almost when they’ve showed in the large numbers in the small screen. They fight as a team, not as an individual, even if that was what Mando was aiming to do. He felt the burden of sin for giving up the Child to the Imperium who stolen their system, and forced them to become outcasts.
It was his cross to go to get the child, but not fight the whole battle on his own. In fact, it seems that it is also his biggest flaw, to be too proud to go to ask help of his brethren, because that’s what I would have done in his shoes.
Mando mentioned to one of his brothers, as he was leaving, that they would have to move their hideout now that they had helped him--so possibly he was initially reluctant to involve them, especially in what was, to him, a "sin" (whichever part of his actions that refers to). It may be the Way not to let a brother fight alone, but he might not feel confident enough to ask it of them. It doesn't have to be pride. In fact, I would like to think (as deeper characterization) that Mando
did consider the option of going to them for help, but felt unsure that they
would help him based on the confrontation they had had earlier--and in the end, he was not only grateful but
relieved that they really had come to his rescue. Reaffirming that they indeed considered him a brother. For him, the rescue was also a resounding statement of loyalty to him on their part, one that had been lacking up until now.
But I realize none of that is stated. It could be pure invention on my part. It's simply the explanation
I would write, based on what's there. That's what I like about movies and television--it leaves enough gaps of ambiguity that you can link the bits together with your own imagination!
My other thought when I saw this was, are we sure he is Mandalorian by birth? He's a foundling, after all--so are they just picking up random orphans and raising them as Mandalorians, possibly to boost their numbers, or are they actually finding
Mandalorian orphans? And is everyone there a foundling? Or just him? My guess would be, not everyone there is one, since in the first episode Mando felt the need to tell the Armorer, "I was a foundling," as if it was something special she would not have automatically known.
Just the main ideas circulating in my head right now about this!
