Even now, not bubbly (5)
I believe the answer is:
still
I believe this is a double definition.
'even now' is the first definition.
(thesaurus)
'not bubbly' is the second definition.
('still' is the opposite to 'bubbly')
(Other definitions for still that I've seen before include "Where to make spirits" , "Silence" , "Always" , "Source of alcohol" , "Not going anywhere" .)
