The best word to describe Gallahan is clingy. He's too overprotective, and doesn't want his precious son to have contact with any dangers. He's even cautious with his own sons' cousins.

His son is the light of his life and his one treasure. He'll do anything to keep his baby out of harms way.

He's constantly fussing and worrying. Even if his son is just going to the garden or the bathroom, he's there.

And it doesn't matter what you think! He knows what's best for his little angel, you don't!
