The plot is thickening nicely. Arwen may be able to contribute more insight into human nature, which is something the elves sometimes lack.

The digger thing is weird - my 2-year-old grand nephew was watching some Thomas The Tank Engine episodes yesterday, and every time I looked up something seemed to be falling off a truck or a bridge, trains were running away, etc., to an extent that I began to think that the island of Sodor must be in the Thunderbirds universe... You sure as hell wouldn't get me using public transport there...
