Ross and Joey continue to explore their own emotional unavailability which seems to cut deeper with every new rejection, no matter how small.  Ross helps Joey combat this by brainstorming a practical solution (new method alerrrt) to reverse the urge to ghost once ghosted. They're both still learning to drop their bullshit pride, and decide to challenge themselves by - *cringe* - double-texting. They realize this faux pas may not only circumvent the initial "playground" stage of talking to someone, but also serve as an empowering antidote in the face of rejection.
