Kate never told Humphrey "I love you"

Hello everyone. I'm very sorry for the lack up posts, I was very busy. Today I chose to talk about Kate. I've realized that she had never told Humphrey the following line "I love you".

 I'm not sure why though, it would make her relationship with Humphrey much more stronger. Yes there are probably fan videos on Youtube where she has said that to Humphrey, but she never said it even in the sequal.

 Humphrey has told Kate that line when after the scene with a caribou stampie, and Kate getting knocked out on the ground. Although after she woke up, she didn't tell Humphrey that she loves her. She probably whispered it into Humphrey's ear, but non of us could hear it.

 Most fan probably don't care about this, but it's hard to find something to talk about related to Alpha and Omega that not many people know about. So please be a big support and leave your suggestions in the comments.
