Dil is commonly depicted as being curious and playful, with the typical tendency to grab out for various items that capture his attention (including jewelry, Angelica's doll Cynthia, and hair) and may strike others as being selfish, but to an innocent and unknowing extent due to his young age. Albeit Dil is incapable of speech, he's able to communicate through simple "baby talk" terminology involving the few mispronounced words he does know and his nicknames for those around him, and is strongly attached to his elder brother. Tommy cares deeply for Dil and frequently makes precautionary measures during the infants' fantasized ventures to protect his brother from harm, defending him against any hazards or Angelica.
