Author's summary: Jack Harkness really wasn't expecting to see Sarah Jane Smith behind door number one.
Characters/Pairings: Jack, Ianto, Gwen, Sarah Jane, Clyde, Luke, Maria
Word Count: ~2,500 words
Recced because: This is sweet, fresh, and fun. Set after S2 of TW and S1 of SJA (so it's a bit scrambled by S4 of DW, but never mind that), Jack tries to recover a dangerous alien artifact and is rather surprised to meet Sarah Jane and her gang of teenagers, especially her teenage son, Luke. All the character voices are spot-on, with Ianto's internal observations on the whole thing especially hilarious, and the dialogue just sparkles. A very enjoyable piece.
