There's one mech he's like this with:
I. I don't know. I just returned to reread "All hail Megatron" bc I remembered that Prowl was there. The thing I didn't remember, however, is him being so much kinder.
Sure he is still pretty serious, strategic and clearly far from innocent. But when he's around Jazz, he is suddenly..also.. supportive?? I wasn't expecting that from him.
I guess Jazz is that special one, who can made Prowl to show, that he is capable of love and care and kindness.
