Who is going after Brian Fraser in Outlander: Blood of My Blood season 1 episode 9, and why does Murtagh save him?

Brian Fraser's life is put in danger in Outlander: Blood of My Blood season 1 episode 9. During the tynchal, instead of joining the hunt, he is delegated to become the beater after another fight with Lord Lovat. While in the woods doing the job of a beater begrudgingly, someone shoots an arrow at him. The Gallowglass, a crew of local mercenaries-for-hire, is coming after him.
But before the assassins can get to him, Brian's cousin, Murtagh, arrives to save him. The cousins have been on the outs since the Beltane Festival after Murtagh feels like Brian betrayed him for getting with Ellen MacKenzie. Which is why Brian is shocked to find Murtagh saving him from the Gallowglass, but according to Murtagh, no one is allowed to kill Brian but him.
Brian and Murtagh escape the woods and the Gallowglass on their horses at the end of Outlander: Blood of My Blood season 1 episode 9. However, it's still a mystery why the assassins are after him since Colum has given his word to Ellen that he will not cause any harm to Brian if she promises to leave him. And, throughout the series, Brian hasn't had any enemies who would try to kill him.
Does Ellen break up with Brian in Outlander: Blood of My Blood season 1 episode 9?

A threat to his life is not the only thing Brian is facing in Outlander: Blood of My Blood season 1 episode 9. He's also nursing a broken heart after Ellen MacKenzie makes an impossible decision to break up with him, saying that she doesn't love him. Despite Brian begging, and even if he's telling the truth that they love each other, Ellen's mind is already made up, and it's her only way to protect him.
Ellen has to cut ties with Brian for good because Colum has found out about the two of them, no thanks to Dougal, after what happened at the Jacobite meeting. Colum wants to kill Brian Fraser, not only for touching his sister, but for endangering Clan MacKenzie's agreement with Clan Grant. However, Ellen threatens to disown Colum if he ever causes Brian any harm.
In the end, the siblings make an agreement. Ellen will cut any ties with Brian if Colum swears that he will not kill or have anybody kill Brian Fraser. Whether or not Colum has kept his word is a mystery since the mercenaries, who also happen to be at Braemar's festivities, have come after Brian's head.
Outlander: Blood of My Blood season 1 episode 9: What happens to Henry and Julia, and what are they planning?

Thanks to Brian and Julia's scheming, Lord Lovat allows Julia and baby William to go to Braemar with them in Outlander: Blood of My Blood season 1 episode 9. It allows Julia and the baby to reunite with Henry during the festivities and, with Ned Gowan's help, meet in secret to formulate a plan to escape.
Ned has been a good friend to Henry and has promised to help him escape the Grants for good, especially after learning how the late Grant laird and Arch Bug deceived Henry. At the end of Outlander: Blood of My Blood season 1 episode 9, Henry and Julia conspired to meet outside of Leathers, and she would leave a mark for him.
