What if Lucy died?

Does Tim have to know this?

Around 9pm Tim came home from Angela's.
Ta: hey dad!
Tamara hugged her father
T: hey princess, I hope you have a good excuse for skipping school. You know I don't like it when you skip school.
Ta: I know but Katie stood there, I couldn't just walk into school like nothing happened.
T: it's okay, what are you cooking?
Ta: moms favorite.
T: with her recipe?
Ta: yup, just took a half-hour looking for it.
T: That's sweet of you, so... did you and Lucas went to the movies?
Ta: erm no we didn't, but about that...
T: exhales deep*
Ta: we're a couple, but not official yet? I think I can call it like that. But I won't be out of the house all the time yk, I can't let you here by yourself all day...
Tim laughs
T: Well, it's not like you could get rid of me so easily yk, it's my responsibility to keep you safe.
Ta: I know dad.
They hugged, after dinner Tim and Tamara played a game "who am I?" And went to bed. The next morning Tamara got up early to curl her hair and do a cute makeup look but not to heavy, she picked out an outfit:
