After secretly returning back to Weiss's room, Elise immediately handed her a bag filled with various plants and liquid. Among the huge amount of herbs that the just destroyed dark orginisation had, Weiss had specially mentioned a few to Elise. And this bag that she had brought back had some of those valuable herbs.
After getting her hands on this, even though there was no change in her expression, with her extremely well practiced "Weiss's face reading" skill, Elise was able to see that her mistress Weiss was extremely happy with this result.
This fact made her very happy too. So while Weiss started to check out the quality and the condition of the herbs, Elise happily started to tell her about how the mission went.
