Becoming a father changes Silco in ways no one could have anticipated, certainly not himself. But it had changed him, and with that, it changed the underground. Silco by no means stopped being a dangerous man, but he focused more on making the world better for Jink than he did on his own goals. From there comes the Baby Blue Protocols. Silco comes to rule the underground even more than he did before, and with that comes the strict rule that nobody touches his daughter. Even those not directly under Silco's rule come to respect this. Things change as Jinx gets older and is able to defend herself; if she starts a fight, then of course, the other party can retaliate, but everyone still understands exactly who they are dealing with and who stands behind her.
Things get messy when time travel becomes involved.
Vander and Powder wake up in a version of the Lanes they don't recognize, and anyone who sees them coming immediately runs away. Even if they weren't faced with Vander back from the dead, nobody wants to deal with getting too close to Zaun's princess while she's so small and fragile. Eventually, Sevika shows up all grumpy about having to deal with this mess, grumbling about them scaring the shit out of half the Lanes and bringing them to Silco. Vader is, of course, on high alert, trying to be prepared for anything through his old heartbreak, but Silco is kind with Powder and cordial with him, if not a bit cold still, and Vander allows himself to relax slightly.
And then Jinx jumps down from the rafters, and things go to shit again.
