Several scenes involving Anakin and Ahsoka in the series' pilot movie and episodes tend to be very heartwarming.
"You're reckless, little one. You never would have made it as Obi-Wan's Padawan. But you might make it as mine."
Jabba and his relationship with his son, Rotta.
Rotta himself, he genuinely likes Anakin and seems to outright adore Ahsoka.
While comforting Ahsoka, Anakin mentions his mentor and father-figure Qui-Gon Jinn as a wise Jedi.
During the battle on Christophsis a panicking R2 goes over to one of the clone troopers, who pats him on the head despite being the middle of a firefight. You can almost hear the trooper thinking "It's okay buddy. We got this."
It is revealed that Yoda was the one who assigned Ahsoka to Anakin. Keep in mind that Yoda was the few Jedi who believed in Anakin and by doing this Yoda hoped that when the time came for Ahsoka to go off on her own, Anakin would understand that he need not be attached and feel so protective of those he loved.
When Anakin has to leave the troopers to fend for themselves in order to complete the mission Rex doesn't begrudge him for a single second; this is war, the troopers are doing their jobs and Anakin has to do his. In contrast to Anakin clearly not being happy about the situation Rex accepts things as they are and reassures Anakin that he's making the right call, no matter how bad the situation for the troopers is.
