"How I Met Your Mother" returns tonight at 8 p.m., EST, after an episode that saw Robin's father come into the picture remarried but not to Robin's knowledge. Barney finally gains the approval of Robin's dad (Ray Wise) and Robin comes to grips with her dad's new life and new bride. We also saw Ted's feelings about marriage weighting him down so he's decided to put off of his energy into the planning of the wedding of Ted and Robin.

On this upcoming episode after accepting Barney's marriage proposal and the engagement finally becoming official, Robin moves on to getting used to the new piece of hardware that now sits on her hand. We see Robin getting more and more comfortable with her engagement ring but is uncomfortable with the "Power of the Bling" that comes with her ring.

After proposing to Robin, Barney moves his focus on to Ted's new relationship. He begs Ted to continue to see his younger, wilder new girlfriend ("Pretty Little Liars" Ashley Benson). While Barney is in favor, the rest of the gang is not sold on Ted's new love interest. But there is a reason behind Barney's interest in Ted's love life. What is it? And why can't Ted's new girlfriend go into MacLaren's.
