I agree, very good call. I thought exactly the same thing and she clearly loved animals. As all the best people do in life. A splash a yell would likely result (?)
I feel strongly now that as the police have flagged the gravest sensitive context/back story & data on all of this, and are seemingly so adamant about Nicola being nearer the sea, that THIS is exactly the key. Think about what we know and who has been interviewed and how they have reacted in the light of this, quite carefully. Some have been criticised, even, (unfairly) for being impersonal, numb even angry. How might you react if you feared the worst and then seemingly had that confirmed in your mind?
The answer therefore may lie within the video upthread I believe. The focus on the cars/dash-dam, main road exit, and all the resource focus here, shows they believe a good chance Nicola exited here. The focus on the area towards the sea, which is currently foxing Peter F as seemingly makes no sense, she CAN'T have travelled there, he says. Oh, but she can IF this is closer to where she really entered the river.
