No specific fic in mind, this is a general squee.
We can look forward to a deluge of Tony/Peter slash when Homecoming comes out in July and Peter is better characterized.
I love their age difference, where Tony is experienced, brash and sure-footed... until he gets sick.
I'm brand new to the Avengers (loved RDJ via Sherlock Holmes), do we know if RDJ is doing the press junket for Homecoming? I'm guessing not, so as to keep the attention on Tom Holland.
