Just then, Alex came while carrying with him a quilt covered in artistic work as Alex explain that this quilt was a family heirloom of which has been passed on through many generations, each of patchwork was stitch from past and present and it was his turn when at the very moment, Tess accidentally spilled ice cream all over the quilt Tess strongly apologize but Alex wasn't upset or mad as he says that he'll just take it home and put in the washing machine with his other laundry before when Addison said "See ya tomorrow then Alex". Later at home, Alex throws the quilt in the wash and pours in quite a lot of laundry detergent and starts up the machine before as he leaves the room.

The next morning, Addison and Tess are tuning up both robots; Eureka and Gyro, while Addison felt hot and wised there was a way to cool off when Tess suggest that about trying out the Refreshmaster on herself. Addison always wanted to try a person and agrees but just then, Alex rushed in shouting his quilt was gone as the two girls ask what happen. Alex wasn't sure though, he put it the washing machine but he couldn't find it anywhere when the laundry was done. Addison figure there had to a reason so they go to Alex's apartment to investigate. Later, Addison, Tess and Alex check the laundry room for clues when Addison notice some sheets hanging by the window and asked Alex why those sheets are there. His mom put them there to dry quicker in the heat and then, Addison thought that maybe Alex's mom hang the quilt up thinking it was a bed sheet but when they looked, the quilt was nowhere to be found they asked Alex's mom but she hadn't seen it either. If the quilt wasn't hang up by the window then maybe it was blow outside in the wind however, Alex said that's impossible since there not even a single breeze today. Addison than says "We made a mistake. We need to take a break, think it through and try again." but she was still feeling pretty hot at the moment so she decided to freshen up in the Refreshmaster before they would get back on the case as Addison asked to Gyro to prepare the sub-zero temperature setting as its part of the procedure.
