fic: specific; Bruce is trolling people

[neffi3.livejournal.com]

Hi!
I'm looking for a (most likely) multi-chaptered fic, where Bruce Banner is trolling people, posted most likely on fanfiction.net (although livejournal is also possible). I remember there was an interview with Avengers and the person leading the interview started asking Natasha uncomfortable questions (miscarriage implied) and Bruce did/said something to shift attention elsewhere/on himself. Another scene was when agents from SHIELD came to the Avengers towet to bring Clint in for questioning or something and Bruce volunteered to go instead. But he made conditions - there had to be a song played (which had a certain frequency and caused some pipes to vibrate and brake to create chaos). Tony caught on what Bruce was planning and almost gave him away, but managed to save it with some flirtatious remark.
Thank you in andvance for your help.

Tony raises Steve's daughter

[bookwyrm124.livejournal.com]

Hello all! I've been looking for a story and I'm beginning to think I'm mushing two together. What I remeber is: Steve and Sharon are together. Steve disappears through a portal or rift, etc. Sharon finds out she's pregnant and tells Tony she has no interest in raising the baby. Tony adopts her. Steve comes back 5, 10 years later and Tony panics that Steve will want to take the little girl.

Any ideas? Is this one story or actually two?

Thanks!
