"Ah, about that…" Hailee just remembered that she hadn't said anything about this to Lis. "The plan is, this weekend Ramon and I will visit my family."
"The Tatum family," Lis said. She already knew where Hailee was from and did some background check and found some irregularities there, it's just that Lis didn't want to spoil what Hailee and Ramon had planned and was waiting for them to explain this on their own.
No, Lis expected Hailee to explain this, because it was certain that Ramon would not say anything and if Lis asked the wrong question, this would actually trigger an argument with Ramon like before, therefore, she chose to shut up, while learning more about her future daughter-in-law.
"Ah, yes..." Hailee was a little surprised because Lis knew about her family. But, after a while she realized that given their status, it was impossible to cover this up, it's just that for some reason Hailee was not in a state of wanting to explain about her family.
