"Groups of three.  I remember."  She glanced up at Dolohov, who was watching her intently.  "Lucius... I know another partner is unexpected.  I know you were... displeased... when I flirted with him the first time I visited him in Azkaban."  She reached for Antonin’s hand, and he gave it.  "But his presence in my thoughts when I was in Quirrell’s root cellar, when I could not feel my bond to the rest of you... it kept me grounded.  It reminded me that I was not alone," Hermione said.  Obviously moved, Antonin pulled her gently into his arms and she gave him a hug.
