At the start of the episode why was Clara acting so weird? and had a lot of post it notes with mentions of previous episodes?

Also at the end Danny was looking at the iPad and there was a reflection - has anybody got a screenshot/screengrab of this? wondering who it was

She wanted to tell Danny the whole truth about her travels with the Doctor (including the last few months when she had supposedly stopped).

Presumably she'd kept it kind of vague after The Caretaker.

Not sure about the first question: maybe she was trying to decide between all the recent adventures and her love for Danny?

I think the reflection was the youngster he met - the one he killed with the grenade when he was a soldier.

Yep the reflection was the young boy Danny killed in battle. When I saw that I wondered 'has the kid been deleted yet?'

Maybe Clara was about to tell him she was pregnant?

Could be.

i'm expecting to see a further reveal related to that scene. Don't forget, in the trailer we saw Clara saying 'Clara Oswald' never existed and we still haven't seen that scene happen yet.

Did I miss something? I only see reflection of Danny crying in the IPAD.

The child he killed pops up behind him.
