Violet was never late. She checked her watch and alarm clocks were accurate on a daily basis and knew to the minute how long everyday tasks would take her. Her dad's weren't quite as regimented, she understood that meals could be a little delayed and accepted that sometimes the universe conspired to try and delay her.
Lena, having lived at the whims of her crazy 'aunt' for fifteen years, had very little concept of time. If the sun was up she knew it was daytime and if it was down then it was night, that was about it. She could pick up her phone and lose track of the hours she spent on it, not even bothering to look at the clock on the screen.
Violet We're going to be late.
Huey Lena?
Violet She went for a walk, left her phone at home and we're waiting for her to get back so dad can drive us.
Huey I'll tell Webby.
Violet Lena is the one who made these plans, I know she wants to see Webby before you head out on your latest adventure. Why is it so hard for her to be on time?
Huey She's not used to being responsible for herself. Magica used to tell her when to go and do things, she just hasn't learnt that there can be consequences for not paying attention to the time.
Violet Should I help to reinforce that idea? Teach her the importance of being on time, then provide a repercussion when she is late?
Huey You can't punish your sister.
Violet Our dads aren't comfortable with enforcing the rules with her yet.
Huey You should try to talk through the problem with her.
Violet Or I could tell her that Webby already left, because she didn't come home on time.
Huey That would be a lie.
Violet Not if she arrives home after your departure. I assume Mr McDuck is eager to leave.
Huey Well, yes but... I think Webby is working on a diversion with Dewey to delay him.
Violet I will need you to stop them.
Huey I can't stop Webby!
Violet Then just stop Dewey. Please.
Huey I suppose if their plan is dangerous I could intervene, but only to protect them.
Violet Acceptable.
