Hi. As far as I understand your figure, the red box below is the `Cell`.

That is the reason Cell return

> 

```
    h_1 (batch, hidden_size): tensor containing the next hidden state for each element in the batch
    c_1 (batch, hidden_size): tensor containing the next cell state for each element in the batch

```
