He can't thank him when he was about to lose his wife and child at the same time so that he could live
If you were him, can you say thank you when someone helped you but almost cost their life. Also the baby, it almost risked the baby's life. I think keith is still not over the fact that the two of them almost died while saving him.
I'm not telling him to say the exact word he has a right to me angry but after shouting he could at least hug him says don't u ever do that again instead of just stomping off .... Just an opinion not trying to fight ~
I do get ur point
The word is "thank you " u should be thanking him!
