Warning: contains spoilers.

An eyewitness ability to accurately recall key details of an event can be adversely affected by anxiety.

If said event was stressful to watch, testimony can become unreliable.

Its called Weapon Focus and its a totally legitimate, actual, true, real-life thing.

Look, I was stressed about poor Steve and in the grip of Balaclava Focus.

Thats my excuse anyway.

Spoilers, obviously, ahead… Look at Huntleys eyebrows here.

Not dark are they?

This may become relevant later.

The moment Steve leaves Huntleys office, Huntley calls Jimmy Lakewell.

The third floor is now listed as vacant for refurbishment.

But, confusingly, not quite fitting our knowledge of Nick Huntley.

This chap looks bigger.

And check out these eyebrows.

Not pale at all.

Ill tell you who is stouter than Nick Huntley and has dark eyebrows the security guard!

Who else knew Steve was in that lift?

Only Nick Huntley and the security guard, that we know of.

Anyone in Steves office also knew he was on his way to Huntleys office, including newcomer Jamie.

Did he, or somebody else, call ahead to tip off the attacker that Steve was coming?

Why was the attacker already in the building?

Perhaps that explains Nick hiding behind all those moving boxes?
