|Pairing:||Brandon Foster and Mike Foster|
|Kind of Pairing:||Father-son relationship|
After divorcing from Stef, Mike didn't fight for custody over Brandon, leading to Brandon being raised primarily by Stef and Lena, his stepmother. The bond between Brandon and Mike is often friendly and good, but appears a little fragile at times, for example when Mike starts drinking alcohol again, when Brandon sleeps with Dani and when Mike decides to foster AJ. During season 1, Brandon lives with Mike for a while in order to have time to get over Callie. Mike's struggles with Brandon both raise tensions between Mike and Stef and strengthens their bond.
