The big boss (sorry horrible with names) was talking to the other one about the possible lawsuit because of the bar fight... Basically he tells them they are throwing him a deal... 30 days off and docked 7 vacation days... but he doesn't like it... he later faxes the commissioners office telling them where to stick it... for that, he gets his trial plus suspended starting immediately... end of showing he is leaving firehouse with his stuff in a box...
Franco has an ex girlfriend show up... Sean tells her Franco is dead because Franco doesn't want to see her... she is "psycho" stabbed him twice before... she leaves but before she goes leaves her number with Sean, who later meets her in a bar... one thing leads to another and they end up "together"... she is a little wild, if you get my drift...

she later comes back to the firehouse and finds Franco... she brings a child with her and tells Franco he is her father... he denies it over and over but before they get a call out, he gets the DNA results and he is the girl's father...
The firefighter (don't remember name) who has had the gentleman asking him to go with him for a drink finally goes, explaining when he gets there that he is not homosexual... the guy says neither is he and that he is actually engaged... he gets a good chuckle out of it... when his fiancee arrives they have a long bout of PDA and then she kisses the firefighter thanking him... Then they tell him that they want to include him in a threesome... we later find out he hid in the restroom an hour and half waiting for them to leave the bar...
Tommy had the biggest storyline... he starts out talking to Franco about this woman he met in a bar that he has been "visiting" but doesn't know her name... he is using her, basically... later it shows him outside her house, finishing off a bottle of booze and she calls him asking him where he is... she has seen his truck outside... when he goes in, she goes to take a shower and he looks through her mail to try to find her name but no luck, he finds two different names and neither seems to "fit" her... later they are "together" and she tells him she loves him... he in a moment of passion responds the same...
Tommy also goes on a date with his cousins widow... they talk about her son and whether she will find anyone... Tommy finds out the lady he saw her with before was actually her psychic not her lover...

She drinks quite a bit and gets drunk when they get to her place Tommy has convinced her that her son is tutoring to make the money she found (the son later tells her the same thing because Tommy is on the phone and tells him what to say)... anyway, she kisses Tommy in the truck and they lip lock pretty good... When Tommy gets home, his cousin's ghost is waiting for him... glad to find out that she is not seeing a woman worried that she may see a man... Tommy gets a guilty look on his face which his cousin catches.... Tommy tells him he didn't have a look...
While Tommy was waiting for his nameless woman in the shower, his daughter called wanting to go to a concert in the city with "the Murphy boy"... Tommy says no and hangs up... Tommy runs into his exwife at home and tells her she needs to be taking care of the children more... says she is too busy with her boyfriend... they talk about the concert and both agree they told their daughter no... needless to say, it was not a good conversation... later that night, the firehouse is called to an accident... an SUV is flipped over on his side... the driver had been drinking... the other car involved was on its roof... Tommy starts over to it and sees them pull "the Murphy boy" out... he starts to run over but the fire chief stops him telling him to stay at the other car... Tommy dials his daughter's cellphone and hears it ringing at the site of the wreck... it takes about 5 or 6 others to hold him back... they tell him she is hurt bad but is alive... Tommy, the chief and the poem writer rush to the hospital... she is alive but has had a head trauma... Tommy's ex comes in with her boyfriend... Tommy is not happy about that and starts to fight with him when he buts in... Later he is out smoking and his ex comes out... they get into it again and he yells that she is too busy trying to get some to take care of her children... A physician comes out to talk to them but has no real news, the boyfriend buts in again and that is all Tommy could take... he shouts for him to leave and the ex tells him to leave... Tommy sits down and she sits by him... he picks her hand up and they hold hands... later Tommy goes to his church and speaks to his cousin the father... they talk about how everything has changed and church had always been their security... it was a very heavy conversation with Tommy saying he knew God had a reason but if something happened to his little girl, he was going to want to know why... as he is leaving, his cousin and some other ghosts are sitting in the back pews... he glimpses down one and sees his daughter... he starts, looks back and she is gone... he goes and lights and candle for her and asks God for his help telling him that he would come back to church... it ends with him pausing in front of the alter and leaving...
Whew... hope that helps!
