by

In Season 8, Episode 15 of 911, you’ll see a host of guest stars gracing the screen, such as Anthony Cistaro, Chris Wu, and others.

As a dedicated fan of the ABC series, I found myself on the edge of my seat during the most recent episode. This thrilling installment followed the show’s core group of first responders, who were thrust into a harrowing situation when some members of the Los Angeles Fire Department 118 found themselves trapped while battling a biohazardous lab fire.

The new episode, “Lab Rats,” marks the start of a lengthy hiatus for the latest 911 season.

Declan Pratt – Denny Wilson

In the show, Denny Wilson, portrayed by Declan Pratt, is not biologically related to the main characters Hen, Karen Wilson, and Mara. Instead, he grew up under their care as they adopted him shortly after his birth, with his biological mother placing him for adoption. Additionally, Denny shares a foster family bond with Mara.

As a dedicated cinephile, I must confess that Chris Pratt has graced the screen on numerous occasions for 911. Apart from this, his most significant role can be found in “Driven,” a production by Passionflix.
