rear its ugly head

rear its ugly head idiom
Appear. This phrase is used only of something undesirable or unpleasant, as in The interview went very well until a question about his academic record reared its ugly head. This expression was first recorded in slightly different form in Anthony Trollope's Barchester Towers (1857): “Rebellion had already reared her hideous head.”
