just re-read that portion in c101 in chinese.
"I think that child will meet with wendy one day"
"next time, hope to get along with him better"
The 2nd phase could mean that Grandine hopes Natsu and Wendy will get along better the next time they meet
or
it could mean that Grandine hopes to get along better with natsu the next they meet.
