They go stumbling in and there's a new element in an Arcade story as his minions bodyswap with Excalibur. Ray is taken out of action by possession, lest she break the story. (There's some linkage with Inferno setup there, but it's not clear to me what's going on. Interesting fact: she thinks Baby X is called Nathan. She should know, since she was with the team around the time he was born.) Kitty remains free, and is able to convey to Courtney the information necessary to bodyswap everyone back.
And... in the soap opera bits: Meggan nearly manages to seduce Nightcrawler (I'm going to need to carefully examine their next appearances); Saturnyne swaps places with Courtney; and Brian takes some flowers to !Courtney. Kissing happens. Chart might need updating.
Issue #4 wins my prize for best cover yet:
Alan Davis writes about it here, and spoils the mystery. It was just a cheap gag because the first issue was all setup.
Well. Chris Claremont takes several hundred Brit points by having it be a plot point in #4 that Marks and Spencers refused to take credit card payments (that's why Kitty had to use cash to pay, which was subsequently found to be bogus).
I almost forgive him for having Captain Britain say "strewth". Curiously urbandictionary makes the same mistake, and perhaps for the same reason Claremont did. Yes, it does appear in episode 1 of Monty Python's Flying Circus, said by a man from Guildford. But it is put in the mouth of a man who is called "Bruce Foster" and has, for that one syllable he utters, a bad Australian accent.
It is clarified that the lighthouse is on the western coast of England. This consists of two distinct stretches from the Solway Firth to the River Dee; and then from the the Severn Estuary down to Cornwall. My guess would be that it is on this second, south-western stretch, because that would be more Celtic; but somewhere in Cumbria is always an option. It appears to be not that far from a major town. Kitty calls it the "middle of nowhere", but then she is a Chicago girl who spent much of the last year in suburban New York.
