Leading lady Sophia Bush is departing the series and will not return to play Erin Lindsay for another full season, although Bush may return for a guest arc to bring Lindsay’s story to a natural end.
All things considered, fans of P.D. may be especially glad to have his familiar face returning, given the big change that we already know is in store for Season 5.
We may get to see Dawson and Lindsay interacting at least one more time before Bush leaves.
If Chicago P.D. doesn’t cast a new leading lady to fill Sophia Bush’s shoes, we may see the other stars like Jon Seda getting more time in the spotlight in Season 5 and onward.
