Season 18 of Keeping Up with the Kardashians got off to an explosive start with Kim Kardashian West and Kourtney Kardashian getting into a physical fight at the end of last weeks premiere. This week we saw the aftermath of their altercation and a close up of Kim's scars.

After Kim commented that she and Khloe were the only ones who are reliable and have work ethic, Kourtney took to defending herself. The verbal insults quickly turned physical, with Kourtney throwing a boxed water at her sister and then initiating the first blows. Kim quickly fought back getting in several seemingly hard kicks and punches. While it looked like Kim dominated the fight, Kim was the only one shown physically harmed with several scars.

This week fans got to see the tail end of the fight. Turns out the snippet ending the premiere was just the beginning. The sisters fought for several minutes, exchanging blows with one another. In some moments Kourtney was able to scratch and dig her nails into Kim, leaving visible bleeding scars on several parts of her body. See photos below:

Once Kim and Kourtney were separated, Khloe tried to calm Kourtney down while Kendall followed suit with Kim in another area of Khloe's home. Khloe's attempts to bring peace to her home, and keep baby True sleeping, weren't going smoothly as things got intense between her and Kourtney too. Khloe exclaimed, "Are you crazy?... Did you just try to hit me?" She turned her back towards the camera causing viewers not to see what was occurring. "Kourtney if I hit you you would be knocked the f*** out." That would have been a sure way to make sure their bickering didn't wake up her daughter.

Kourtney and Kim exchanged a few more words until the eldest sister left. Khloe took to cleaning her wall, Kendall joked it was supposed to be her fight, Kim tended to her wounds all while they tried to figure out how did it build-up to that moment. When Kris Jenner was informed of the argument, she was too occupied with being stressed about Kylie not being able to fly to Paris and having too much fun to understand the level of discord between her daughters. By the end of this week's episode, Kourtney apologized to Kim and eventually sat down with her younger sisters and their friends, Malika and Khadijah, who acted as mediators, to hash out their differences. Hopefully, the worst is over and the sisters can go back to their regular level of arguments.
