If you mean the feathers, no. Her passive specifically states they fall behind her primary target.

Yes and no.

Yes, her w throws out extra feathers that fly to the enemies the bolt's attack(Rakan throws out one for each of the targets hit too, leading to a max of 6 little blade feathers) increasing it by 20% of the auto's damage, 40% if Rakan is nearby.

No, her passive does not make the bolts do the same as her main auto.
