Obi-Wan might think it off if he's having a vision of Anakin that that vision would include one with hair he hadn't worn this short since he was still a padawan and there's no little braid dangling out of it or one who was clearly not dressed as a Jedi though some components of what he was wearing may have come from a Jedi's wardrobe.

For Anakin, it's Obi-Wan's presence in the Force--even if tinged with a sorrow Anakin can't put a name to--and the sound of his voice that decides him. Obi-Wan has aged, yes, but so has Ahsoka and...well, everyone else he ever knew, he supposes. But it's still Obi-Wan. And his old Master has always been something of a stable point in the universe for Anakin.

The urge to close the distance between them and wrap his arms around him is almost overwhelming, but Anakin manages to keep his pace sedate and his hands at his sides.

"We should talk."
