It probably has something to do with that, at least, as he keeps the arm that would be in the way of her standing against his side up, controlling various winds that way.

And if he's missed any plants, its totally because his attention is on the winds moving across the table, rather than plants above them.

And to dove, maybe not quite noticed, but the fun he's having has shifted a bit - its a little deeper, a little warmer.

... And maybe a little warmer yet as he casually drops his arm over her shoulders. Yup. Comfy.
