the commercials does seemed to be tied to her past, the first ep is about the stark toaster when it's about wanda's parents being killed by a stark industries bomb and a 2nd mortar ticking like the toaster but not exploding leaving petro and wanda trapped , 2nd commercial is about strucker with the tagline 'he'll make time for you' which i gathered to mean when wanda was recruited by strucker and the third with the hydra soap which might implied when they go through the hydra brainwash procedure.
