She Abandoned Her Sister Having a 'Bathroom Emergency' to Catch a Flight

We've got another dividing the internet on our hands! 

A woman named Olivia and her stepsister Ella were traveling for a wedding and had a layover before their flight to Washington when Ella had to use the bathroom for an "emergency."

Olivia said “Don’t do it. We board in 20 minutes. Go on the plane.” Her sister said she wasn't going to make it and asked Olivia to watch her backpack. Olivia said no, she's getting on the plane...

Olivia boards and gets a text from Ella saying “I’m having horrible constipation. Please get off the plane and wait for me.”

Olivia said “I will let the flight attendant know, but if you can’t get on this plane, I will see you in Washington.”

Ella missed the flight and they later met up in Washington. Ella is not speaking to Olivia. Was Olivia in the wrong?
