This article tells us about the relationship between Brock and Bubbles in Pokemon Cartoons.

Bubbles vs. May

Later, at the challenge, Bubbles looks at Brock, before she does her battle. When Bubbles loses, Brock, along with Blossom, Buttercup and Isabella, is shocked. After Bubbles rushes out the door, Brock follows her, with Blossom and Buttercup following him. Brock complains that Bubbles shouldn't go, but Bubbles leaves anyway. Brock cries over that.
