According to the recent updates ruhi is hating the kid because in her pov it's abhiras kid. As her behaviour now a days it wouldn't be astonishing if she plans to harm the baby or tries to kill him just to hurt abhira . So it could be a possible track where she tries to kill or harm the baby and Rohit spillsout the truth just to save his baby.
It would be heartbreaking to see abhira after the truth revelation but will be nice to finally get rid of this whole baby tamasha .
