Miranda Rae Mayo says her TV son is “a joy” on set of Chicago Fire
As Chicago Fire fan favorites Kelly Severide (Taylor Kinney) and Stella Kidd (Miranda Rae Mayo) continue navigating the euphoric highs
and lows of being foster parents to a teen boy, Isaiah (Hero Hunter), Mayo reveals that Stella might be feeling a tad jealous of the father-son vibes around the household.

NBC Insider chatted with Mayo about Stellaride’s exciting new chapter as foster parents, which has gone a bit differently for each of the parents. Isaiah came to the firefighters after his mother’s health prevented her from being his guardian, leading him to initially shy away
from them. Severide managed to bridge the gap with video games and some take-your-child-to-work excitement, but Isaiah has taken a little longer to lay down his defenses around Stella.
“I think it’s one of those things where she really wants it to happen. But you can’t force it,” Mayo explained to NBC Insider. “And Kelly, I think generally speaking, things move smoothly for him. You know what I mean? Like he’s just kind of overall [a smooth presence], and he doesn’t have a lot of expectation when it comes to Isaiah. So I think that is what made it easier for them to connect.”
Stella has admitted as much to Severide, but he’s encouraged her to stay patient as Isaiah settles down. Fortunately for Stella and her relationship with Isaiah, the envy has started to subside as she continues to learn about Isaiah’s chronically ill mother.
