Transformers Animated/Heartwarming

"Bumblebee: You let'em leak as much as you need to. We're here, and you're safe. So whatever it is, you can always talk to us. We'll listen."
 * In the episode "Return of the Headmaster" when Bumblebee and Bulkhead finally ask Sari if she's okay after . Sari explains as much angrily, then bursts into tears. Having seen this before, Bulkhead comments that her eyes are leaking. Bumblebee picks her up and says:

"Omega Supreme: I am Omega Supreme. I am yours to command. I am your pupil. Your dependent. Your obedient servant. Ratchet: I am Ratchet. I am... your friend."
 * The reconciliation between Sari and her father at the beginning of Season Three after  was just adorable fluff.
 * Omega Supreme's introduction to Ratchet, his new (but unwilling) mentor.

"Sari: I know, I know. It's too dangerous. It's always too dangerous. Optimus Prime: I was going to say, it's more important for you to protect your father and your fellow organics. Sari: (sheepishly) Oh. Sorry."
 * At the end of the series, the reaction Omega Supreme gets when he.
 * Don't you dare forget this exchange between Optimus Prime and Sari. (at the very end of the series no less, a definite show of how their relationship has changed)


 * The human Prowl playing peek-a-boo with a baby in "Human Error, Part 1." It's brief, but very cute.
