Ultimately, the Titan gets to tango (2,4)
I believe the answer is:
at last
'ultimately' is the definition.
(synonyms)
'titan gets to tango' is the wordplay.
'titan' becomes 'atlas' (Atlas is an example).
'gets' means one lot of letters go next to another.
'to tango' becomes 'T' (phonetic alphabet: alpha, bravo, charlie etc.).
'atlas'+'t'='AT LAST'
'the' is the link.
(Other definitions for at last that I've seen before include "Where a snob worked" , "Where cobbler located" , "Finally, ultimately" , "Finally, having waited a long time" , "Finally, after a long wait" .)
