Anakin is, for lack of a better word, gobsmacked.
His mother, who he hasn't seen for five years, is standing before him. She is dressed in rich brown cloth, tears in her eyes and smiles splitting her face.
". . . mom?"
"Well, will you look at that!" Obi-Wan exclaims in exaggerated surprise, eyebrows hiking up to his hairline. "Of all the luck, meeting your mother here, on this completely random planet, in this very market. What a happy accident!" he carefully annunciates, loudly enough to gather several odd looks from neighboring shoppers. He then throws out his arm, pointing his arm dramatically towards a nearby advertisement. "Oh look! A scenic tour of the Bengazi forest! I think I will take their two week tour and meditate on . . . life. Alone. I will see you at the launch platform when it is time to depart!" and with that, Bendu Master Obi-Wan Kenobi, horrible actor and sneaky-bastard extraordinaire is off.
Shimi Skywalker watches as he disappears into the crowd with a polite frown of confusion. Anakin is still in shock. After a moment of contemplation, she turns back to her son.
"Hello Anakin."
Mother and son spend the next hour wrapped in a hug in the middle of the marketplace and the rest of the 'jedi spiritual retreat' catching each other up on their respective lives.
Shimi finds herself saddened about the death of Qui-gon, but also cannot deny that small bit of selfish happiness that the thoughtful young master Kenobi is raising (and guarding, and teaching, and protecting) her son rather the single-minded master Jinn. Admittedly, she has had limited contact with him. But it is obvious (in Anakin's stories and tone of voice) that they genuinely care about each other; none of this 'there is no emotion' nonsense.
If someone else absolutely had to raise her child, she is glad it was him.
Even if he is a little weird.
