Ela yes she is shown as so blinded in her jealousy that she is upto such foolish acts..and yes hoshiyaar saved her yesterday coz he understands the gravity of going against jodha...even he has realized her importance to jalal but ofcourse will not tell rukku...yesterday was a forewarning by hoshiyaar about what is to follow...and i agree with Aku here that she is not going to think or plan but on the spur of the moment come up with pregnancy idea not at all thinking about what next and her desperation and foolishness is going to take her down
