[Grammar] will be

[raymondaliasapollyon]

Hi,

Is the "will be" correct in the following?

A: I don't think John will be available this weekend.
B: Believe me. He will be.

I'd appreciate your help.

If "really" is inserted, are the following possibilities all correct?

A: I don't think John will be available this weekend.
B: Believe me. He really will be./He will really be./He will be really.

If a different adverb is used instead of really, will your judgment change?

It is a lot smaller than it eventually will be / it will eventually be / it will be eventually.

It is a lot smaller than it eventually will be / it will eventually be / it will be eventually.

The third is the most natural. I'm afraid I can't explain why.

Be careful here. The positioning of adverbs can be a tricky thing to work out. It depends on the sense of what you want to say, not on the form.

In other words, you can't come up with a rule that says: adverbs are best placed before/after will be, for example. It all depends.
