Whilst the introductions had been taking place in the past, Hermione had been trapped within her own mind, contemplating different scenarios her family were currently in. She observed horrifying events she had originally witnessed during the second wizarding war, only this time it was her children, her nieces, her nephews, and her friend's children facing the fate of those who had died in battle or else had survived it broken and wounded. She saw Fred taking the place of his namesake, crushed under a wall, Roxanne grieving at the loss of her twin, one of her ears missing just like her father. She saw Hagrid carrying the dead bodies of first James and then Albus as Voldemort cruelly proclaimed them as cowards who were killed escaping. Worst of all she saw her children, Rose, sweet little Rosie taking on her role as Bellatrix tortured her, hitting her with the cruciatus curse again and again, holding a knife to her delicate throat, blood dripping from where it touched her flesh. Then she saw her youngest, her little baby Hugo as brains attacked him in the Department of Mysteries, his agonising screams blending in with that of the other children. She watched scene after scene as her worst memories played out, children taking on the roles of their parents or those they were similar too, never able to get close to them so she could help them or to ease their pain, forced to watch from a distance as they died in brutal ways, never knowing they were safe, and it was all just a terrifying dream.
Whilst Hermione was trapped within her mind, Madam Pomfrey had discovered a spell which would allow one person to enter another's mind to persuade them to leave it. It had been decided that Ron would be the one to enter Hermione's mind as he was the one who was closest to her what with him been her soul mate and all. The spell was simple enough but had no reversal, once in her mind the only way Ron would wake up would be when Hermione did, meaning should she never come round Ron would be as good as dead because his soul would be trapped within Hermione's body.
To do the spell Ron had to lay on a bed next to his beloved wife as Madam Pomfrey waved her wand first over his heart and then over Hermione's in a complex pattern chanting the words "coeant in unum corpus et animus, qui coeunt and sanandum" repeatedly until he felt his eyes drop, and the sensation of been lighter than air and free. He then raised out of his own body hovering in the air like a transparent ghost before slowly sinking down into the body of his lover…
Note: coeant in unum corpus et animus, qui coeunt and sanandum – means mind and soul unite in one body to heal one's mate in Latin.
