Abha might have found karan in that jungle at night where their car was stopped
Thats y they didn't showed how abha reached to ujjain but they directly showed her in ujjain
I think something has happened between that scene
Also in maha episode's promo sid tells everything to dushyant he might have done that to help abha so that he can help abha to get SB back from him by playing cards on them only
I hope u all r undrstn
