Suletta is still trying to mope, but her own stomach betrays her. She needs nourishment, but it's not just her body which needs nourishment, but also her soul. She has been cutting herself off from her friends, and she has been feeling worse because of that. Her friends are able to help connect her back into reality, and they do so without having to keep bringing up recent events, but by just focusing on there hare and now. You can watch as Suletta is restored to life as she takes a sip and savors it. Being with her friends is also delicious for her heart.
And into this moment steps the leader of the group, who has been wallowing in his own form of misery, but unlike Suletta, his friends have been unaware of it. The truth has been a burden, and knowing what was going on with Nika hurts everyone in different ways. Chuchu is hurt by Nika's betrayal, while Suletta sees the best in Nika, and Till points out that the only way they can find out the truth is by talking to Nika. So much of the second cour of G Witch especially has been driven by characters not talking to each other. Martin kept this a secret, Nika bottled everything up, Norea was bottling her feelings up until this episode, Suletta was avoiding her friends, Miorine kept her distance from Suletta, and then cast her aside to try and save her but without telling anything truthful to her, etc. In this context, Till's proposal to actually talk to one another about their feeling represents a radical but genuine path to cut through everything that has been plaguing the characters and to find a genuine path forward
