'pull it together' is the definition.
I can't judge whether this definition defines the answer.

'dump fiancee at last during drink' is the wordplay.
'dump' becomes 'crap' (the act of defecation).
'at last' says to take the final letters.
'during' indicates putting letters inside.
'drink' becomes 'sup' (to sup is to drink).
The last letter of 'fiancee' is 'e'.
'crap'+'e'='crape'
'crape' going within 'sup' is 'SCRAPE UP'.

'to' is the link.
