to demonstrate that Sonny is still sexy, desirable, and not past his expiration date! I understand that they are attracted to each other. I mean, flies like 💩 but Sonny wasn't at all upset with Natalia over her homophobic comments--yet he raked Ava over the coals for releasing the recording.
He's an inconsistent, oily-haired, fake ass Phony Soprano, mumbling goober. With the assistance of Viagra, we are stuck with Sonny as a "romantic lead" until MB retires or they cut him to save $$$
ETA: I'd rather see them spend $ on a new character like Natalia (the diversity is NEEDED) vs continuingly bringing back played out characters like Holly Sutton. Seriously, what has she added to this story other than flirting and throwing shade? I wish it were Skye or hell--even Jennifer Smith. Holly sucks!!!!
