Chicago fire season finale (spoilers)

[TerraNotSoFirma2]

3 episodes ago was the episode with the bomb in the hospital, where Shay collapsed at the end.
2 episodes ago, it was like the bomb had never happened. Shay is perfectly fine, no mention of bomb?

Did I miss an episode or something?

And the finale tonight OMG!

Anyone else watching?

The conclusion to the bomb story was carried over to another series called Chicago PD that hasn't been shown in the UK yet.

Ah that makes sense now, Thank you.
