Uh-oh, Nii-san foiled her plan.

Untranslated bubble seems to have some wordplay I can't quite choke down at the moment: she's referring to finally "welcoming" Hige-san with a verb that could either mean "as a guest" or "as a new member of the family".

Also that little brother's a jerk.

He seems to genuinly want to just help out his sister here. I just see a case of "Too dumb to live" cause he's obviously gonna die after this page.

Yes, I think you're right. I found this 兄に嫁を迎える meaning st like my brother let his wife live in with him.
