Tbh I still see that as brushing off, or deflection if she is a murderer. She’s ignored her colleague trying to raise a concern with her and not taken it seriously. Which is why the colleague quickly backs off saying ‘ignore me’ because Lucy doesn’t want to entertain it.I don’t think it’s that she brushed it off - she said in response to ignore me I’m speculating by saying:
“ Ms Letby said: “Well (Child C) was tiny, obviously compromised in utero. (Child D) septic. It’s (Child A) I can’t get my head round.”
In my opinion, I don’t think that’s brushing it off. She came across like she felt she understood why C and D died but came across unsure as to why child A died from that text. I dunno why she would say that about child A if she was brushing it off.
I just see the final reply as her going that bit further to firmly plant in her colleague’s mind that there was nothing odd going on. Not having a reason for baby A doesn’t matter so much if she has two different reasons for the other two. She’s reaffirmed to her colleague they were all different.
In the context of her being a murder suspect and lots of other colleagues finding those collapses very unusual, I find it very suspicious that Lucy did not show any concern. (I appreciate that may change further down the line, but so far we don’t have any evidence of that).
