Walk into the Choral Clinic after you have 3 hearts with Chloe, Taylor, Irene, and Ramsey.
The two kids are busy bouncing on the clinic's patient beds until Irene yells at them for coming to the clinic to make trouble. Chloe and Taylor run through the clinic but Irene can't catch them.
Taylor thinks they're being pretty clever to be able to escape the old nurse. Chloe suggests that they should go try to bother her grandfather next.
Part 2
Walk to the Celesta Church grounds after you have Jin and Owen at 2 or more hearts, and you have seen Part 1.
Chloe had sneaked back to the Blacksmith's shop, taken a few things from Ramsey, and then slinked back to the plaza to meet up with her playmate. Taylor managed to sneak a bottle of medicine out of the clinic. Chloe wants to hide their stolen items but then the two troublemakers are caught by Ramsey and Irene!
Irene thinks they're trouble making has gone on for long enough. She demands they confess up to their little prank and return the items they took. Ramsey seems pretty disappointed in Chloe as well. Irene makes the kids feel guilty when she asks if the two kids do this because they don't like them.
Chloe and Taylor start to cry because they do like them. Chloe tells her grandfather that she'll be good, and Taylor is upset because Irene is always there to make him healthy.
Jin eventually shows up to smooth things out. The older people are just worried about the kids; they don't actually dislike Chloe and Taylor. The two kids apologize to Irene and Ramsey.
