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.
When I saw this for the first time, I thought Khyle was just being himself; I was partially right, but it seems like Your mother hung herself is a meme, and yes, it implies Carnage, thus the profile picture of the troll in this comic. The context is a little long, but you can read it here if you're interested.
i let the site automatically name the artist based in the pixiv url, no idea if this is the proper naming convention or not, the katakana reads dogē
We try to use the artist's actual name or handle whenever possible. The stacc name or username from another account will typically be included as a qualifier to keep it from being ambiguous. The artist tag for this post was just changed, so you can refer to it as an example.
