Er, OK. I must have missed a critical detail at some point because I don't understand why the Old Man being in Kal'tsit's room is a problem. It's not like their relationship is a secret to Folinic and Wafarin anyway, and she called him to her room in the first place.
What is she going to do herself? Kill herself? She doesn't need to go anywhere further than that shotgun.
Look at it like this, if she wanted to kill herself she would have done it. Only Elster can do it, but she keeps failing at getting over to her so Ariane is going to drag Elster to her chamber pod herself.
Going by DaveyGamersLocker's comment It's Squeak Squad/Mouse Attack Kirby. It seems to be specifically a reference to the minigame Smash ride, so I'm adding the tag.
