Charlie arrives back at his flat via the lift (presumably after driving up in his lorry) and hangs his jacket up. Then he notices that the piano's gone and he starts shouting for his brother. Liam, incredibly still there, says he sold the piano. And returned for a fun little confrontation with his brother? Charlie asks if the money went up Liam's "sodding arm" and Liam says he's been clean for two days. "Two days? Well, happy anniversary!" spits Charlie, and Liam is all, "Well, how long have you been clean?" Charlie says nothing, because touché. Liam says Karen was going to leave him and take Meghan. But she's got an uncle in Australia who has a job for him, and there's a rehab clinic he can go to; he just needed the money to get them there. "I have to do this. I have to take care of myself, for them. For my family." "I'm your family!" shouts Charlie, which could be a big part of the reason why Liam's high all the time, if you ask me.
Outside on the street, Charlie chases his brother and wants to know what about the band, what about the song, and Liam just says that he needs to do this and he'll give Charlie a call when things settle down for him. "For you? What about me?" Charlie should have tattooed "what about me?" on his knuckles instead, you know. "What about my family?" yells Charlie as his brother heads into the Underground station, past one of those logos that makes me think of those old Vuarnet shirts.
Back on the island, the Volunteer Fire Brigade has all but extinguished the fire. And Charlie is STILL standing there looking at Aaron. And now that the diversion he created is pretty much over, Charlie decides that now would be a good time for a second baby-snatching attempt. Claire's still standing over there, clearly waiting for her cue to turn around and see Charlie absconding with a screaming Aaron in his arms. She starts yelling and chasing Charlie, and her screams alert Locke, who comes running too, to tag-team intervene as Charlie stands in the surf of Lostaway Beach, saying he just wants to save Aaron.
I know Christianity in general and Catholicism in particular seem to be the default faiths of people on television, but right at this moment, I'm glad Charlie wasn't, say, Jewish. Can you imagine if he was trying to perform an emergency bris instead of a baptism?
