She historically has kept her distance, despite Kelly's multiple attempts to get her sister involved in her drama. Kelly has publicly angsted in the past over how Gina never signs up for her ruse cruises and won't be her personal army online. However, Kelly mutilating her legs into a double above the knee amputation forced Gina to pay attention to her psycho twin sister and stay in proximity for a while. She was posting for Kelly's behalf on Instagram, visiting her in the hospital and at home, probably helping her get groceries and things during her "recovery", etc. Kelly is addicted to attention; that's why she does everything she does both online and to her own body. For her the double amputation was a "win" because she reaped the greatest harvest of attention from friends, family, and medical professionals she'd ever received in her entire life.
But now the bloom is off the rose. The attention has died down. Those friends, family, and medical professionals are moving on with their own lives, lives that don't involve Kelly. The idea that Gina would soon be travelling halfway across the globe and therefore not available for Kelly to call up and cry at to come over and pay her attention seems to have thrown Kelly into a particular panic. It seems like on impulse she came up with an equal parts vindictive and retarded attempt to throw a roadblock into Gina's travel plans by declaring her sister was having a mental health crisis and needed to be apprehended. Then she either thought better of it and took it down shortly thereafter, or Gina called her and bitched her out to make her take it down.
