A commonplace, practical reply, [out of] the train of his own disturbed ideas

[Irelia20150604]

The quotation comes from Charlotte Brontë – Jane Eyre (Chap. 37) | Genius

Quotation: “…Will she not depart as suddenly as she came? To-morrow, I fear I shall find her no more.” (said Mr. R)

A commonplace, practical reply, out of the train of his own disturbed ideas, was, I was sure, the best and most reassuring for him in this frame of mind. I passed my finger over his eyebrows, and remarked that they were scorched, and that I would apply something which would make them grow as broad and black as ever.

Hi everyone! Does the bold part mean “I was sure that a commonplace, practical reply irrelevant to the train of his own disturbed ideas was the best…”?

"unrelated to" might be better than 'irrelevant to'; but basically you understand.

I'm sure you see the point: If a child comes running and says to you, "A monster is chasing me" the best reply might NOT be, "Oh, I don't think he's very near", but rather, "Let me wipe your face with a damp cloth." One is choosing to disregard a line of thinking, rather than, in effect, give it validity.

I see. Thank you for your explanation!
