PORTIA. If this were true, then should I know this secret.

Question

I grant I am a woman, but withal
A woman that Lord Brutus took to wife.300
I grant I am a woman, but withal
A woman well reputed, Cato’s daughter.

Think you I am no stronger than my sex,
Being so fathered and so husbanded?
Tell me your counsels; I will not disclose 'em.305
I have made strong proof of my constancy,
Giving myself a voluntary wound

Here in the thigh. Can I bear that with patience,
And not my husband’s secrets?

BRUTUS. O ye gods,310
Render me worthy of this noble wife!

[Knocking within]

Hark, hark, one knocks. Portia, go in a while,
And by and by thy bosom shall partake
The secrets of my heart.315
All my engagements I will construe to thee,
All the charactery of my sad brows.
Leave me with haste.

Which line from the text best supports the conclusion that Brutus intends to tell Portia about his plans?

"If this were true, then should I know this secret. / I grant I am a woman, but withal / A woman that Lord Brutus took to wife."
"I have made strong proof of my constancy, / Giving myself a voluntary wound / Here in the thigh. Can I bear that with patience, / And not my husband’s secrets?"
"Hark, hark, one knocks. Portia, go in a while,”
"And by and by thy bosom shall partake / The secrets of my heart."

Answer 1

The line that best supports the conclusion that Brutus intends to tell Portia about his plans is:

"And by and by thy bosom shall partake / The secrets of my heart."

This line clearly indicates Brutus's intention to share his secrets with Portia, reinforcing the idea that he is planning to confide in her.
