Dear English-speakers, especialy the native ones, I need your help very very much.

I'm doing some translations and I need help with some parts. Please tell me, what are the images that occur to you when you hear the phrase or how would you explain the meaning of the phrase to a foreigner.

Thank you very much!

1. But if again
I held thee captive as I did ere now
Stalling to pass my fingers through the last
Of midnight tendrils.

What is midnight tendrils here? I am particularly interested in this one... and how can you 'pass' your fingers through them? Is it a comparison? For what?

2. I'm blessed
With the ability to rend a grown man tongue-tied.

Rend a grown man tongue-tied here. Please explain.

3. Goodbye.
And so I've said too much and not enough
And so the play is finally at an end
You never had the care to call my bluff
and so I must be pleased to be your friend

The line You never had the care to call my bluff. I assume it defines the 'play' in the previous line, but maybe I am wrong? Maybe this is an independent phrase? If yes, then can you please explain the meaning?

That's all for now.

THANK YOU!
