Go to the Pillars
This chapter starts right off the last one without any cutscene or break in between. Follow the linear path down to the beach. When you reach the pillars, interact with the marked one, then follow along the linear path.
Fight
When you reach the boats, you will then have another one on one melee fight. You can treat this the same as the prior melee fights, where you wait for the opponent to attack, dodge it, then attack yourself. There will be a points where you need to mash 
in between sections of the fight, but otherwise it is mechanically the same as prior ones. Once it is over, the chapter will end.
This finishes Chapter 45: The Beach in The Last of Us Part 2. Next is Chapter 46: Epilogue.

Took me a few tries to get thru this fight. One time I got to see Ellie get killed and then another time once I got thru it, it was good to see both women came to their senses and went their separate ways alive. I think the key to getting thru the fight is that once the directions are prompted to act immediately. If you hesitate and wait say 2 or 3 seconds after each prompt, Ellie gets killed by Abby. Good to see that Lev, Ellie, and Abby all walk away to live out their lives in one piece. Seems like at the end of the day, Abby just can’t seem to get a break in life, losing her father, her boyfriend and friends along the way. I guess I be angry too if it happened to me.
