Well technically she could have gone back to Jakku after everything but chooses to go to Luke to start her training. Also in STAR WARS Luke was pretty much forced to take his voyage after his Aunt and Uncle were killed seeing as how there was nothing for him.
And sarcasm is hard to gauge in 2016 m8. I just assume everyone is serious now.
She went to Ireland to find Luke after the moment where she accepted her call. Luke also refused his call in Ben’s hut, and was reluctant until his family was killed. They share the refusal and reluctant acceptance of the call.
Sarcasm around here can be tough, just felt the need to clarify.
