Thunderbirds are Go - the rest of Season 1

The Thunderbird Shadow has a motorbike that drops out of the bottom. No
doubt the toy comes with a Captain America figure.

So, just to wrap up this one, since episode-by-episode reviews were becoming a little samey:

The second half of the series upped the stakes with the Hood making repeated attacks on International Rescue - including engineering a change of leadership in the Global Defence Force in order to force IR to stand down and hand over their tech - and Kayo under increasing threat of being revealed as his niece. In the season finale he makes his big push, but is thwarted ultimately by Kayo and Lady Penelope.

It took a while to get Kayo her Thunderbird, but it's a nifty little number and she's been no slouch without it, which has been good to see. The vast preponderance of Theresa Gallaghers in the world notwithstanding, this has been a decent little series and a worthy successor to a well-loved but decidedly flawed original.
