They'd be old fics, I'd think, given the age of the shows. Back in the 1990s, QL crossovers were extremely common (show is kind made for them). I figure whatever it is that causes Sam to leap in, it almost has to be something he needs Al and future-knowledge for - MacGyver is too much of a superhero to do otherwise. Seriously, I was thinking how much faith people who know him have in MacGyver's abilities and of Sam looking at them like you "you expect me to what?" when they expect him to get them out of a scrape.

happy (belated) 60th birthday
