Were not done with that.

Kidd (Miranda Rae Mayo) took being the emergency contact really personally and seriously.

Are they going to reconnect?HAAS:Yes!

We played obviously the Severide-Lindsay storyline early on in the show.

We could have another ripple, but right now there are no plans to revisit Lindsay-Severide.

that honestly launched four seasons of another show.

And that meant a lot to Voight.

Its not just open-ended discord and hostility.

And however long it lasts is however long it lasts because hes not going to break me.

He of all people is not going to take it from me.
