Later, Frank justifies his tough-love approach to his associates.
Lenny was a great guy with a whole lot of flaws, he explains.
And one of them was letting his daughter get away with whatever she wanted.
So when he asked me to look out for her, he knew what he was signing up for.
I think thats why he asked me.
Youre not her father!
She justlost her father.
A father she didnt know existed until a few years ago.
Maybe its not just bail she was looking for.
Listen, Im working on my eulogy.
So are they gonna shoot off guns or something?
Tess asks about her dads funeral.
But he will have an honor guard, Frank confirms.
He hated bagpipes, she responds.
Yeah, but he loved the old dogs bursting into tears.
Thats what bagpipes do, Frank says.
He then invites her to a family dinner and bids her farewell.
Theres also someone who ate here with us over the years but who wont be back, he says.
Lenny Ross was my oldest friend, my closest confidant, my getaway driver.
And I lost him this week.
And it hurts like hell.
And save me a seat at your table, and Ill seeya on down the road.
