I have a headcanon...that has ripped my heart out but I'm keeping brave ^^;.
What if...part of the reason Master Plo "adopted" Ahsoka was because he's been longing for a child of his own, Jedi Code be damned. So, when he first finds Little 'Soka, he just had to take her in as his own daughter. Anakin, Wolffe, and the other clones are like her brothers and Obi-Wan is like her uncle.
....Master Plo, please give my heart back.
