"There's something wrong with me but I'm not going to tell anyone, just go on risking others lives in the process". It's one of the dumbest things.
I also am not feeling Harry. He's just...there. He doesn't add anything interesting, IMO. Just being Athena's kid is not enough. I also don't really care about him wanting to be a firefighter. It feels like an impulsive, almost childish decision coming from him, right up there with "I quit high school". (So how did he get into the fire academy without a high school diploma?) I don't think they need Harry attached to the 118 for Athena to be connected to it. She's friends with all of them and they have a shared love for Bobby. That is enough.
I got to admit, Eddie has been working my nerves since the Shannon2.0 storyline. I'd be ok with sending him back to Texas for good.
The show really is a mess right now. I wish they could clean it up but that starts in the writer's room and someone willing to tell the boss "Space is a stupid idea".
