You may want to double-check that.

I remembered hearing no such thing from Tom's mouth but just to be sure, I checked the GFII transcript which can be found in The Godfather Trilogy link below.

Here's the dialogue:

CUT TO: The inside of a hotel room. ROCCO stands in front of the door as MICHAEL opens it. MICHAEL shakes his hand and pats him on the back. NERI shuts the door as MICHAEL rubs his eyes.

MICHAEL: Al - could you get me a wet towel?
KAY know I'm back? [TOM nods.] What about my boy -did you get him something for Christmas?

TOM: I took care of it.

MICHAEL: What was it so I'll know?

TOM: Well, it was a little car with an electric motor that he can ride in - it's nice.

[MICHAEL pours himself a glass of water. NERI comes to him with a wet towel.]

MICHAEL: Thank you, Al. Fellas, could you step outside for a minute?

[ROCCO opens the door and steps outside, NERI follows.]

Where's my brother?

TOM: ROTH got out on a private boat, he's in a hospital in Miami. Had a stroke but he recovered okay. Your BODYGUARD's dead.

MICHAEL: I asked about FREDO.

TOM: I think he got out - he must be somewhere in New York.

MICHAEL: Alright - I want you to get in touch with him - I know he's scared - tell him everything's all right. Tell him I know ROTH misled him - and he didn't know they were planing to kill me.

[TOM nods.]

Um -- they can come in now.

TOM: Uh - there is something else.

What follows is where Tom informs Mike of Kay's miscarriage.

There is NO discussion from Tom as to what Roth had led Fredo to believe would happen to Michael.
