Lancelot ducks into a small shop near the station to pick up some powerade and a cold drink for himself, waving off Faolan and paying for it. The bright blue colour for it is perhaps a clue it isn't the most natural of drinks, but its point is to hydrate and wire you through and it certainly does that.

The trip is about 15 minutes through to hammersmith station, a five minute walk to change lines then another short two stops. Hammersmith is a little busy, and Shepherds Bush itself moderately so, but once they begin walking they're heading away from the city centre anyway. Lancelot is squinting up at the sky, half debating how long the heat will last and half basking in it. It's probably a good thing Lily is inside, the kitchen tiles at least will stay cool.
