Unless one's name is actually Malfoy, it's entirely unwise to put one's life in Lucius' hands. It's not so much that he protects himself first - though he's certainly high on the list - so much as the fact that most of his non-magical education was focused on the fact that loyalty to the family is paramount. Which is, he muses, why as irritating as the arrival of family from the future is, he still insists upon making certain they aren't likely to run afoul of danger.

Danger, in this case, quite frequently lies in the Ministry. Danger for the noncompliant could quite easily come from Lucius himself, or the people he counts as close friends. Bella among them.

"Indeed." Astronomy wasn't precisely pressed upon Malfoy heirs, of course, but Lucius had had what many considered an unfortunate interest in divination as a boy; he'd plotted more than one star chart in his day. "I understand from my initial conversation with young Scorpius than my son is named Draco." Which, he thinks, is another quite relevant constellation.

"But I think I'll hold off on the celebrations, as much as I'm certain it relieves my father." He ought to be married by now, after all. He'd already been born when his father was his age.
